DA9132
High-Performance, Dual-Channel DC-DC Converter for
Mobile and Portable Applications
General Description
DA9132 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.
DA9132 integrates two single-phase buck converters, each phase requiring a small external 0.22 µH
inductor. Each buck is capable of delivering up to 3 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 DA9132 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 DA9132 in the
same application.
DA9132 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.
■
Configurable GPIOs support a range of features including I2C, DVC and Power-Good indicator.
