DA9132-A

High-Performance, Dual-Channel DC-DC

Converter for Automotive Applications

General Description

DA9132-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.

DA9132-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 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-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 DA9132-A in the

same application.

DA9132-A 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.
