SAW ES – step-down switching voltage regulator
B30000P80xxY908
Micro DC-DC converter modules
P8012 … P8020
1 Overview
This module family is a 6 MHz (2.8 V version – 3 MHz), 600 mA step-down DC to DC converter, that delivers a
fixed output from an input voltage supply of 2.3 V to 5.5 V. Using a proprietary architecture with synchronous
rectification, the P80xx is capable of delivering a peak efficiency up to 92%, while maintaining efficiency over
80% at load currents as low as 1 mA.
The Pulse Width Modulation (PWM) modulator can be synchronized to an external frequency source. At
moderate and light loads, Pulse Frequency Modulation (PFM) is used to operate the device in Power-Save
Mode with a typical quiescent current of 24 µA. Even with such a low quiescent current, the part exhibits
excellent transient response during large load swings.
At higher loads, the system automatically switches to fixed-frequency control, operating at 6 MHz. In Shutdown
Mode, the supply current drops below 1 µA, reducing power consumption. For applications that require
minimum ripple or fixed frequency, PFM Mode can be disabled using the MODE pin.

7 Operation description
The P80xx module is a 6 MHz, step-down switching voltage regulator available in 600 mA that delivers a fixed
output from an input voltage supply of 2.3 V to 5.5 V. Using a proprietary architecture with synchronous
rectification, the module is capable of delivering a peak efficiency of 92%, while maintaining efficiency over 80%
at load currents as low as 1 mA.
The regulator operates at a nominal fixed frequency of 6 MHz. In addition, the PWM modulator can be
synchronized to an external frequency source.
8 Control scheme
The module uses a proprietary, non-linear, fixed-frequency PWM modulator to deliver a fast load transient
response, while maintaining a constant switching frequency over a wide range of operating conditions. The
regulator performance is independent of the output capacitor ESR, allowing for the use of ceramic output
capacitors. Although this type of operation normally results in a switching frequency that varies with input
voltage and load current, an internal frequency loop holds the switching frequency constant over a large range
of input voltages and load currents.
For very light loads, the module operates in discontinuous current (DCM) single-pulse PFM mode, which
produces low output ripple compared with other PFM architectures. Transition between PWM and PFM is
seamless, allowing for a smooth transition between DCM and CCM.
Combined with exceptional transient response characteristics, the very low quiescent current of the controller
maintains high efficiency; even at very light loads; while preserving fast transient response for applications
requiring tight output regulation.
9 Enable and soft-start
When EN is LOW, all circuits are off and the IC draws ~50 nA of current. When EN is HIGH and VIN is above its
UVLO threshold, the regulator begins a soft-start cycle. The output ramp during soft-start is a fixed slew rate of
50 mV/µs from 0 to 1 VOUT, then 12.5mV/µs until the output reaches its set point. Regardless of the state of the
MODE pin, PFM mode is enabled to prevent current from being discharged from COUT if soft-start begins when
COUT is charged.
In addition, all voltage options can be ordered with a feature that actively discharges FB to ground through a
230 Ω path when EN is LOW. Raising EN above its threshold voltage activates the part and starts the soft-start
cycle. During soft-start, the internal reference is ramped using an exponential RC shape to prevent overshoot of
the output voltage. Current limiting minimizes inrush during soft-start.
The current-limit fault response protects the IC in the event of an over-current condition present during soft-start.
As a result, the IC may fail to start if heavy load is applied during startup and/or if excessive COUT is used.
The current required to charge COUT during soft-start commonly referred to as “displacement current” is given
as:
where dV/dt refers to the soft-start slew rate.
To prevent shut down during soft-start, the following condition
must be met:
where IMAX(DC) is the maximum load current the IC is guaranteed to support.

B30000P80xxY908
Micro DC-DC converter modules
P8012 … P8020
10 MODE pin
Logic 1 on this pin forces the IC to stay in PWM mode. A logic 0 allows the IC to automatically switch to PFM
during light loads. If the MODE pin is toggled with a frequency between 1.3 MHz and 1.7 MHz, the converter
synchronizes its switching frequency to four times the frequency on the MODE pin.
The MODE pin is internally buffered with a Schmitt trigger, which allows the MODE pin to be driven with slow
rise and fall times. An asymmetric duty cycle for frequency synchronization is also permitted as long as the
minimum time below VIL (MAX) or above VIH (MAX) is 100ns.
11 Current limit, fault shutdown and restart
A heavy load or short circuit on the output causes the current in the inductor to increase until a maximum
current threshold is reached in the high-side switch. Upon reaching this point, the high-side switch turns off,
preventing high currents from causing damage. The regulator continues to limit the current cycle-by-cycle. After
16 cycles of current limit, the regulator triggers an over-current fault, causing the regulator to shut down for
about 1.3 ms before attempting a restart.
If the fault is caused by short circuit, the soft-start circuit attempts to restart and produces an over-current fault
after about 200 µs, which results in a duty cycle of less than 15%, limiting power dissipation.
The closed-loop peak-current limit is not the same as the open-loop tested current limit, ILIM(OL), in the Electrical
characteristics table. This is primarily due to the effect of propagation delays of the IC current limit comparator.
12 Under-voltage lockout (UVLO)
When EN is HIGH, the under-voltage lockout keeps the part from operating until the input supply voltage rises
high enough to properly operate. This ensures no misbehaviour of the regulator during start-up or shutdown.
13 Thermal shutdown (TSD)
When the die temperature increases, due to a high load condition and/or a high ambient temperature; the output
switching is disabled until the die temperature falls sufficiently. The junction temperature at which the thermal
shutdown activates is nominally +150 °C with a 15 °C hysteresis.
14 Minimum off-time effect on switching frequency
tOFF (MIN) is 40 ns. This imposes constraints on the maximum VOUT / VIN that the module can provide or the
maximum output voltage it can provide at low VIN while maintaining a fixed switching frequency in PWM mode.
When VIN is LOW, fixed switching is maintained as long as:
The switching frequency drops when the regulator cannot provide sufficient duty cycle at 6 MHz to maintain
regulation.
This occurs when VOUT is 1.82 V and VIN is below 2.7 V at high load currents (see Figure 14-1).

Display of ordering codes for EPCOS products
The ordering code for one and the same EPCOS product can be represented differently in data
sheets, data books, other publications, on the EPCOS website, or in order-related documents such as
shipping notes, order confirmations and product labels. The varying representations of the
ordering codes are due to different processes employed and do not affect the specifications of
the respective products. Detailed information can be found on the Internet under
www.epcos.com/orderingcodes

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical
requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application. As a
rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them
than the customers themselves. For these reasons, it is always ultimately incumbent on the
customer to check and decide whether an EPCOS product with the properties described in the
product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or failure
before the end of their usual service life cannot be completely ruled out in the current state
of the art, even if they are operated as specified. In customer applications requiring a very high
level of operational safety and especially in customer applications in which the malfunction or
failure of an electronic component could endanger human life or health (e.g. in accident
prevention or life-saving systems), it must therefore be ensured by means of suitable design of the
customer application or other action taken by the customer (e.g. installation of protective circuitry
or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or
failure of an electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as hazardous). Useful information on this will be found in our Material
Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed
questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order.
We also reserve the right to discontinue production and delivery of products. Consequently,
we cannot guarantee that all products named in this publication will always be available.
The aforementioned does not apply in the case of individual agreements deviating from the
foregoing for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of
the “General Terms of Delivery for Products and Services in the Electrical Industry”
published by the German Electrical and Electronics Industry Association (ZVEI).
7. The trade names EPCOS, Alu-X, CeraDiode, CeraLink, CeraPlas, CSMP, CSSP, CTVS,
