DA9131-A

High-Performance, Dual-Channel DC-DC

Converter for Automotive Applications

General Description

DA9131-A is an power management IC (PMIC) suitable for supplying CPUs, GPUs, DDR memory

rails in single in-line pin package (SIPP) modules, vehicle infotainment systems, ADAS, automotive

navigation, centre console and telematics.

DA9131-A integrates two single-phase buck converters, each phase requiring a small external

0.22 µH inductor. Each buck is capable of delivering up to 5 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 DA9131-A 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 DA9131-A in the

same application.

DA9131-A has integrated over-temperature and over-current protection for increased system

reliability, without the need for external sensing components.
