Brief Description
Benefits
ZSPM15xx family ICs are controllers designed for
high-current, non-isolated DC/DC step-down point of
load (POL) converters. The ZSPM15xx has a digital
control loop that is optimized for maximum stability
as well as load step and steady-state performance.
•
Factory pre-configured for industry standard
output voltages and currents enabling fast
time-to-market
•
•
•
•
Simplified design and integration
FPGA designer-friendly solution
ZSPM15xx family ICs have a rich set of integrated
fault protection features including over-voltage/
under-voltage, output over-current, and over-temper-
ature protections. To facilitate ease of use, the
ZSPM15xx is pre-programmed and available for
common output voltages. To provide flexibility for the
end-customer, the over-current protection threshold
and the control loop compensation are selectable by
the end-customer to match a number of selected
power stages.

IC Characteristics
Note: The absolute maximum ratings are stress ratings only. The ZSPM15xx might not function or be operable
above the recommended operating conditions. Stresses exceeding the absolute maximum ratings might also
damage the device. In addition, extended exposure to stresses above the recommended operating conditions
might affect device reliability. IDT does not recommend designing to the “Absolute Maximum Ratings.”

Product Summary
2.1. Overview
The ZSPM15xx is a configurable true-digital single-phase PWM controller for high-current, non-isolated DC/DC
supplies. It incorporates a pre-configured digital control loop, which is optimized for different power stages,
bundled with output voltage sensing, average inductor current sensing, and extensive fault monitoring and
handling options.
Several different functional units are incorporated in the device. A dedicated digital control loop is used to provide
fast loop response and optimal output voltage regulation. This includes output voltage sensing, average inductor
current sensing, a digital control law, and a digital pulse-width modulator (DPWM). In parallel, a dedicated,
configurable error handler allows fast detection of error signals and their appropriate handling. A housekeeping
analog-to-digital converter (HKADC) ensures the reliable and efficient measurement of environmental signals,
such as input voltage and temperature.
An application-specific, low-power integrated microcontroller is used to control the overall system. It manages
configuration of the various logic units according to the preprogrammed configuration look-up tables and the
external configuration resistors connected to the CONFIG0 and CONFIG1 pins. These pin-strapping resistors
expedite configuration of the over-current protection threshold, compensation, and output voltage slew rate. A
high-reliability, high-temperature one-time programmable memory (OTP) is used to store configuration
parameters. All required bias and reference voltages are internally derived from the external supply voltage.

Functional Description
3.1. Power Supply Circuitry, Reference Decoupling, and Grounding
The ZSPM15xx incorporates several internal power regulators in order to derive all required supply and bias
voltages from a single external supply voltage of 5.0V. Decoupling capacitors are required at the VDD33, VDD18,
and AVDD18 pins (1.0µF minimum; 4.7µF recommended).
The reference voltages required for operation are generated within the ZSPM15xx. External decoupling must be
provided between the VREFP and ADCVREF pins. Therefore, a 4.7µF capacitor is required at the VREFP pin and
a 100nF capacitor at ADCVREF pin. The two pins should be connected with approximately 50Ω resistance in
order to provide sufficient decoupling between the pins.
Three different ground connections are available on the outside of the package. These should be connected
together to a single ground tie. A differentiation between analog and digital ground is not required.
3.2. Reset/Start-up Behavior
The ZSPM15xx employs an internal power-on-reset (POR) circuit to ensure proper start-up and shut-down with a
changing supply voltage. Once the supply voltage increases above the POR threshold voltage (see section 1.3),
the ZSPM15xx begins the internal start-up process. Upon its completion, the device is ready for operation.
3.3. Digital Power Control
3.3.1.
Overview
The digital power control loop consists of the integral parts required for the control functionality of the ZSPM15xx.
A high-speed analog front-end is used to digitize the output voltage. A digital control core uses the acquired
information to provide duty-cycle information to the PWM, which controls the drive signals to the power stage.
See section 7 for the pre-configured nominal output voltages for the different part codes available in the
ZSPM15xx family.
3.3.2.
Output Voltage Feedback
The voltage feedback signal is sampled with a high-speed analog front-end. The feedback voltage is differentially
measured and subtracted from an internal voltage reference using an error amplifier. A flash ADC is then used to
convert the voltage into its digital equivalent. This is followed by internal digital filtering to improve the system’s
noise rejection.
For some applications, an external feedback divider (R4 and R5; see Figure 4.1) is required to allow for output
voltage operations above the internal reference voltage. For details, refer to the application section 4.3.

Digital Compensator
The sampled output voltage is processed by a digital control loop in order to modulate the DPWM output signals
controlling the power stage. This digital control loop works as a voltage-mode controller using a PID-type
compensation. The basic structure of the controller is shown in Figure 3.1. The proprietary State-Law™ Control
(SLC) concept features two parallel compensators for steady-state operation and fast transient operation. This
allows tuning the compensators individually for the respective needs; i.e., quiet steady state and fast transient
performance. The ZSPM15xx implements fast, reliable switching between the different compensation modes in
order to ensure good transient performance and a quiet steady state.

Two techniques are used to improve transient performance further:
•
Tru-sample Technology™ is used to acquire fast, accurate, and continuous information about the output vol-
tage so that the device can react quickly to any change in output voltage. Tru-sample Technology™ reduces
phase-lag caused by sampling delays, reduces noise sensitivity, and improves transient performance.
A nonlinear gain adjustment is used during large load transients to boost the loop gain and reduce the
settling time.
•
The control loops in the ZSPM15xx are preconfigured and can be selected using a pin-strapping option. A range
of different output capacitors is supported. Refer to section 4.8 for detailed information.

Power Sequencing and the CONTROL Pin
The ZSPM15xx has a set of pre-configured power-sequencing features. The typical sequence of events is shown
in Figure 3.2. The individual values for the delay (tON_DELAY and tOFF_DELAY), ramp time (tON_RISE and tOFF_FALL) and
time-outs (tON_MAX and tOFF_MAX) are listed in section 1.3. Note that the device is slew-rate controlled for tON_RISE
ramping via the pin-strapping options. The slew rate can be selected in the application circuit using the pin-strap
options as explained in section 4.8.
The CONTROL pin is pre-configured for active high operation.
The ZSPM15xx features a power good (PGOOD) output, which can be used to indicate the state of the power rail.
If the output voltage level is above the power good ON threshold, the pin is set to active, indicating a stable output
voltage on the rail.

3.4. Fault Monitoring and Response Generation
The ZSPM15xx monitors various signals during operation and compares them with fault thresholds (see the
“Threshold” column in Table 3.1). If a parameter exceeds a fault threshold, the respective fault signal is asserted
and the ZSPM15xx will disable the output voltage as described below. Note that the ZSPM15xx features internal
blanking times for voltage and temperature faults in order to improve noise-immunity.
Three different response types are supported by the ZSPM15xx. The “low-impedance” response turns off the top
MOSFET and enables the low-side MOSFET; i.e., PWM=0. After tOFF_MAX, both MOSFETs will be turned off,
PWM=Z, DRVEN=0. A “high-impedance” response will disable both MOSFETs instantaneously, PWM=Z. A “soft-
off” response ramps the output voltage down, similar to a power-down operation via the CONTROL pin. After
tOFF_MAX, the controller will disable the power stage by turning both switches off, PWM=Z, DRVEN=0. The
ZSPM15xx features a “hiccup mode,” which allows it to re-enable its output voltage after the fault condition has
been removed.

Output Over/Under-Voltage
To prevent damage to the load, the ZSPM15xx utilizes an output over-voltage protection circuit. The voltage at
VFBP is continuously compared with a preconfigured threshold using a high-speed analog comparator. If the
voltage exceeds the configured threshold, the fault response is generated.
The ZSPM15xx also monitors the output voltage with a lower threshold. If the output voltage falls below the
under-voltage fault level, a fault event is generated.
See section 1.4 for the device-specific threshold levels.
3.4.2.
Output Current Protection
The ZSPM15xx offers cycle-by-cycle average current sensing with configurable over-current protection. A
dedicated ADC is used to provide fast and accurate current information over the switching period. The acquired
information is compared with a selectable over-current threshold to detect faults. DCR current sensing across the
inductor is supported. Additionally, the device uses DCR temperature compensation via the external temperature
sense element. This increases the accuracy of the current sense method by counteracting the significant change
of the DCR over temperature.
The ZSPM15xx continuously monitors the average inductor current and utilizes this information to protect the
power supply against excessive output current. If the average inductor current exceeds the selected over-current
fault threshold, the fault response will be generated. See section 4.7 for instructions for configuring the threshold.

3.4.3.
Input Voltage Protection
The ZSPM15xx continuously monitors the input voltage via the VIN pin. If the input voltage is outside an operation
range defined by a lower and higher input voltage threshold, a fault is detected and a response generated. See
section 1.4 for device-specific specifications for the thresholds.
3.4.4.
Over-Temperature Protection
The ZSPM15xx features two independent temperature measurement units for internal and external temperature
measurement. The internal temperature sensing measures the temperatures inside the ZSPM15xx. Place the
external temperature sense element close to the inductor to measure its temperature. Use a PN-junction as the
external temperature sense element. Small-signal transistors, such the 3904, are widely used for this application.
The ZSPM15xx monitors these internal and external temperature measurements. If either of the temperatures
exceeds the over-temperature threshold (see section 1.3), the fault response will be generated. For additional
information on the external temperature sensing, refer to section 4.6.

4.2. Device-Specific Passive Components
Each product in the ZSPM15xx family requires external device-specific passive components. These are listed in
the following tables.
If specified in the following tables, the feedback divider (R4, R5) is mandatory to achieve the specified output
voltage. The control loop has been optimized for the inductance specified, but inductors from different venders
can be used.
Note: The ZSPM15xx has been optimized for the specific Würth inductors recommended in the following tables
depending on the ZSPM15xx product number. If a different inductor is used, its specifications should be
comparable to the recommended Würth inductor; otherwise the full optimization provided by the ZSPM15xx might
not be achieved. If a different inductor is used, the current sense components (R6, R7, C8) must be recalculated
according to section 4.4.

4.3. Output Voltage Feedback Components
The ZSPM15xx supports output voltage feedback via a resistive feedback divider. However, adding a high-
frequency low-pass filter in the sense path is highly recommended to remove high-frequency disturbances from
the sense signals. Placing these components as close as possible to the ZSPM15xx is recommended. For larger
output voltages, a feedback divider is required. Using resistors with small tolerances is recommended to
guarantee good output voltage accuracy.
Important: The feedback divider components specified in section 1.4 are mandatory if they are specified for the
specific ZSPM15xx product. Components specified as DNP in section 1.4 must not be placed.

The ZSPM15xx supports the loss-less DCR current sense method. The equivalent DC resistance (DCR) of the
inductor is used to measure the inductor current without adding any additional components in the power path. The
technique is based on matching the time constants of the inductor and the parallel low-pass filter. Therefore the
components (R6 and R7) and (C8 and C9) must be selected depending on the selected inductor.

For design guidance using one of the preselected power stages, refer to section 4.2.
Otherwise, the following procedure is recommended:
1.) Set R7’ = 1kΩ
2.) Calculate C8’ = L / (DCR * R7’).
3.) Select capacitor C8 = C9 from the appropriate E-series close to C8.
4.) Recalculate R6 = R7 = L / (DCR * C8) based on the capacitor selected for C8.
4.5. Input Voltage Sensing
The ZSPM15xx supports input voltage sensing for input voltage protection. Therefore a voltage divider between
the input voltage and the VIN pin is required. An optional capacitor C10 can be connected to the VIN pin to help
improve noise immunity. See Table 4.1 for the recommended values for R8, R9, and C10.

4.6. External Temperature Sensing
The ZSPM15xx features external temperature sensing via a PN-junction. Typically, a small signal transistor, such
as the 3904, is used for this purpose. The sense elements should be placed thermally close to the inductor to
allow accurate temperature measurement. For information about the required device parameters, refer to the
electrical specification in section 1.3. An additional capacitor (C11, 100nF) can be used to improve noise
performance.

4.7. CONFIG0 – Over-Current Protection Threshold
The ZSPM15xx can be configured to support a wide range of different over-current protection (OCP) thresholds
based on the user’s selection for the inductor. The over-current threshold voltage between the ISNSP and ISNSN
pins can be configured by using a pull-down resistor (R2) on the CONFIG0 pin. This voltage represents the over-
current threshold because faults are detected by measuring the voltage across the DCR of the selected inductor.
The different configuration options are listed in Table 4.7.

Note that due to the temperature compensation feature, the ZSPM15xx over-current threshold should be based
on the current sense signal at 25°C. Temperature drift is automatically compensated within the device.
Recommendation: For the selection of the over-current threshold voltage, include the tolerance of the inductor’s
DCR and take the parasitic effects of the circuit board layout into account.

4.8. CONFIG1 – Compensation Loop and Output Voltage Slew Rate
The ZSPM15xx controllers can be configured to operate over a wide range of output capacitance. Four ranges of
output capacitance have been specified to match typical customer requirements (see Table 4.8). For each output
capacitance range, an optimized compensation loop can be selected. The appropriate compensator should be
selected based on the application requirements.
Typical performance measurements for both load transient performance and open-loop Bode plots can be found
in section 5.
Note: Using less output capacitance than the minimum capacitance given in Table 4.8 is not recommended.

To achieve the optimal performance for a given output capacitor range, one of four sets of compensation loop
parameters, Comp0 to Comp3, should be selected with a resistor between the CONFIG1 and GND pins. The
compensation loop parameters have been configured to ensure optimal transient performance and good control
loop stability margins.
For each set of compensation loop parameters, there is a choice of seven slew rates for the output voltage during
power-up. The selection of the slew rate can be used to limit the input current of the DC/DC converter while it is
ramping up the output voltage. The current needed to charge the output capacitors increases in direct proportion
to the slew rate.

Typical Performance Data
This section gives typical performance data for the individual products in the ZSPM15xx family. The pre-
programmed compensation loop parameters for the ZSPM15xx have been designed to ensure stability and
optimal transient performance for the specified inductance in combination with one of the four output capacitor
ranges (see Table 4.8).
The transient load steps have been generated with a load resistor and a power MOSFET located on the same
circuit board as the ZSPM15xx and the recommended reference layout. The Evaluation Kit for the specific
ZSPM15xx product can be used to further evaluate the performance of the ZSPM15xx for the four output
capacitor ranges.
