DA9130
High-Performance, 10 A, Dual-Phase DC-DC
Converter for Mobile and Portable Applications
General Description
DA9130 is a power management IC (PMIC) suitable for supplying CPUs, GPUs, DDR memory rails
in single in-line pin package (SIPP) modules, mobile, portable and consumer applications.
DA9130 operates as a single-channel dual-phase buck converter, each phase requiring a small
external 0.22 µH inductor. It is capable of delivering up to 10 A output current at a 0.3 V to 1.9 V
output voltage range. The 2.8 V to 5.5 V input voltage range is suitable for a wide variety of low-
voltage systems.
With remote sensing, the DA9130 guarantees the highest accuracy and supports multiple PCB
routing scenarios without loss of performance.
The pass devices are fully integrated, so no external FETs or Schottky diodes are needed.
A programmable soft start-up can be enabled, which limits the inrush current from the input node and
secures a slope-controlled rail activation.
The dynamic voltage control (DVC) supports adaptive adjustment of the supply voltage dependent on
the processor load, via either a direct register write using the communication interface (I2C-
compatible) or with a programmable input pin.
A configurable GPI allows multiple I2C address selection for multiple instances of DA9130 in the
same application.
DA9130 has integrated over-temperature and over-current protection for increased system reliability,
without the need for external sensing components.

Benefits
■
■
■
High Efficiency buck converters deliver outstanding thermal performance
Fully integrated switching FET’s means no external FETs or Schottky diodes are required
Remote sensing guarantees the highest accuracy and supports multiple PCB routing scenarios
without loss of performance.
■
■
Fully programmable soft-start limits the inrush current from the input to give a slope-controlled
output voltage.
Dynamic voltage control (DVC) enables adaptive adjustment of the device output voltage
depending on the load. This increases efficiency when the downstream circuitry enters low power
or idle mode, resulting in power savings.

Functional Description
4.1 DC-DC Buck Converter
DA9130 operates as a single-channel dual-phase buck converter capable of delivering up to 10 A
output current at a 0.3 V to 1.9 V output voltage range.
The buck converter has two voltage registers. One defines the normal output voltage, while the other
offers an alternative retention voltage. In this way, different application power modes can easily be
supported. The voltage selection can be operated either via GPI or via control interface to guarantee
the maximum flexibility according to the specific host processor status in the application.
When a buck is enabled, its output voltage is monitored and a power good signal indicates that the
buck output voltage has reached a level higher than the VTHR_PG_HYS threshold. The power good
status is lost when the voltage drops below VTHR_PG_DWN or increases above VTHR_HV. The status of the
power good indicator can be read back via I2C from the PG1 status bit. It can be also individually
assigned to any of the GPIOs by setting the GPIO mode registers to PG1 output.
The buck converter is capable of supporting DVC transitions that occur when:
●
●
the active and selected A- or B-voltage is updated to a new target value
the voltage selection is changed from the A- to B-voltage (or B- to A-voltage) using CH1_VSEL
The DVC controller operates in pulse width modulation (PWM) mode with synchronous rectification.
The slew rate of the DVC transition is programmed at 10 mV per 8 µs, 4 µs, 2 µs, 1 µs, or 0.5 µs in
register bits CH1_SR_DVC.
A pull-down resistor (typically 150 Ω) for each phase is always activated unless it is disabled by
setting register bits CH1_PD_DIS to 1.
4.1.1
Switching Frequency
The buck switching frequency can be tuned using register bit OSC_TUNE. The internal 8 MHz
oscillator frequency is tuned in ±160 kHz steps. This impacts the buck converter frequency in steps
of 80 kHz and helps to mitigate possible disturbances to other high frequency systems in the
application.
4.1.2
Operation Modes and Phase Selection
The buck converters can operate in PWM and PFM modes. The operating mode is selected using
register bits CH1_<A or B>_MODE.
Phase shedding automatically changes between 1- and 2-phase operation at a typical current of
2.0 A.
If the automatic operation mode is selected on CH1_<A or B>_MODE, the buck converter
automatically changes between synchronous PWM mode and PFM depending on the load current.
This improves the efficiency across the whole range of output load currents.

4.1.3
Output Voltage Selection
The switching converter can be configured using the I2C interface.
Two output voltages can be pre-configured in registers CH1_<A or B>_VOUT. The output voltage
can be selected by either toggling register bit CH1_VSEL or by re-programming the selected voltage
control register. Both changes will result in ramped voltage transitions. After being enabled, the buck
converter will, by default, use the register settings in CH1_A_VOUT unless the output voltage
selection is configured via the GPI port.
Registers CH1_VMAX limit the output voltage that can be set for each of the respective buck
converters.
Figure 8: Buck Output Voltage Control Concept
4.1.4
Soft Start-Up and Shutdown
To limit in-rush current from VSYS, the buck converter can perform a soft-start after being enabled.
The start-up behavior is a compromise between acceptable inrush current from the battery and turn-
on time. Ramp times can be configured in register CH1_SR_STARTUP. Rates higher than 20 mV/µs
may produce overshoot during the start-up phase, so it should be considered carefully.
A ramped power down can be selected in register bits CH1_SR_SHDN. When no ramp is selected
(immediate power down), the output node will be discharged only by the pull-down resistor, if
enabled in register CH1_PD_DIS.
4.1.5
Current Limit
The integrated current limit protects the power stages and external coil from excessive current. The
buck current limit should be configured to at least 40 % higher than the required maximum output
current.
When the current limit is reached, the buck converter generates an event and an interrupt to the host
processor unless the interrupt has been masked using register M_OC1 in SYS_MASK_1. Register
bit OC_DVC_MASK is used to mask over-current events during DVC transitions.

4.1.6
Resistive Divider
DA9130 can support output voltages higher than 1.9 V using an external resistive divider shown in
Figure 9.
To calculate the output voltage with an external divider, use the following equation
푅1
푉푂푈푇 = 푉
× (1 +
)
푆퐸퐿
푅2
Equation 1
VSEL is the device buck output voltage setting.
Figure 9: Resistive Divider
For example, to program the output voltage to 3.3 V, set VSEL to 1.65 V, and use a 2.2 kΩ resistor
for both R1 and R2, with Cff = 1 nF.
NOTE
The resistors need to be properly selected since the output voltage accuracy will be directly affected by any
errors on the resistors. The voltage across FB1P and FB1N (VSEL) is guaranteed, but not the output voltage
accuracy.
CAUTION
The followings are important notes that need to be considered before using resistive divider on DA9130:
1. Please contact your region's Dialog representative when adopting the resistive divider technique. Dialog
need to prepare a special OTP because incorrect OTP settings may result in a different output voltage
than expected.
2. The total resistance (R1+R2) is less than 40 kΩ.
3. It is recommended that the device is operated in PWM mode only.

Thermal Protection
DA9130 is protected from internal overheating by thermal shutdown.
There are two kinds of flags concerning thermal protection, thermal warning and thermal critical. The
warning flag is asserted when TJ > TWARN and the critical flag is asserted when TJ > TCRIT. When the
critical flag is asserted, Buck1 is shut down immediately.

4.3 Operating Modes
4.3.1
ON
DA9130 is ON when the IC_EN port is higher than VIH_EN and the supply voltage is higher than
VTHR_POR. Once enabled, the host processor can start communicating with DA9130 using the control
interface, after the tIC_EN delay.
4.3.2
OFF
DA9130 is OFF when the IC_EN port is lower than VIL_EN. In OFF, the bucks are always disabled and
LX nodes are pulled down by (typically 150 Ω) internal pull-down resistors.

All features of DA9130 can be controlled with the I2C interface which is enabled or disabled in
register I2C_EN.

GPIO3 functions as the I2C clock and GPIO4 carries all the power manager bidirectional I2C data.
The I2C interface is open-drain supporting multiple devices on a single line. The bus lines have to be
pulled high by external pull-up resistors (2 kΩ to 20 kΩ). The standard frequency of the I2C bus is
1 MHz in fast-mode plus (FM+), 400 kHz in fast-mode, or 100 kHz in standard mode.
4.4.1
I2C Protocol
All data is transmitted across the I2C bus in eight-bit groups. To send a bit, the SDA line is driven
towards the intended state while the SCL is low (a low SDA indicates a zero bit). Once the SDA has
settled, the SCL line is brought high and then low. This pulse on SCL clocks the SDA bit into the
receiver’s shift register.
A two-byte serial protocol is used containing one byte for address and one byte data. Data and
address transfer are transmitted MSB first for both read and write operations. All transmissions begin
with the START condition from the master while the bus is in idle state (the bus is free). It is initiated
by a high to low transition on the SDA line while the SCL is in the high state (a STOP condition is
indicated by a low to high transition on the SDA line while the SCL is in the high state).
SCL
SDA
Figure 12: I2C START and STOP Condition Timing
The I2C bus is monitored for a valid slave address whenever the interface is enabled. It responds
immediately when it receives its own slave address. The acknowledge is done by pulling the SDA
line low during the following clock cycle (white blocks marked with A in Figure 13 and Figure 14).
The protocol for a register write from master to slave consists of a START condition, a slave address
with read/write bit, and the eight-bit register address followed by eight bits of data, terminated by a
STOP condition. DA9130 responds to all bytes with acknowledge (A), see Figure 13.

condition. After receiving the data, the host sends no acknowledge (A*) and terminates the

6.3 Moisture Sensitivity Level
The moisture sensitivity level (MSL) is an indicator for the maximum allowable time period (floor
lifetime) in which a moisture sensitive plastic device, once removed from the dry bag, can be
exposed to an environment with a specified maximum temperature and a maximum relative humidity
before the solder reflow process. The MSL classification is defined in Table 49.
For detailed information on MSL levels refer to the IPC/JEDEC standard J-STD-020, which can be
downloaded from http://www.jedec.org.
The FCQFN package is qualified for MSL 3.

Application Information
The following recommended components are examples selected from requirements of a typical
application.
8.1 Capacitor Selection
Ceramic capacitors are used as bypass capacitors at all VDD and output rails. When selecting a
capacitor, especially for types with high capacitance at smallest physical dimension, the DC bias
characteristic has to be taken into account.

8.2 Inductor Selection
Inductors should be selected based on the following parameters:
●
Rated maximum current
Usually a coil provides two current limits: ISAT specifies the maximum current at which the
inductance drops by 30 % of the nominal value, and IMAX is defined by the maximum power
dissipation and is applied to the effective current.
●
DC resistance
Critical for the converter efficiency and should therefore be minimized.
