High-Performance, 10 A, Dual-Phase DC-DC Converter
High-Performance, 10 A, Dual-Phase DC-DC
Converter General Description
DA9130-A is a power management unit (PMU) 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.
DA9130-A operates as a single-channel dual-phase buck converter, each phase requiring a small
external 0.10 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 2.5 V to 5.5 V input voltage range is suitable for a wide variety of lowvoltage systems.
With remote sensing, the DA9130-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 (I 2Ccompatible) or with a programmable input pin.
A configurable GPI allows multiple I2C address selection for multiple instances of DA9130-A in the
DA9130-A has integrated over-temperature and over-current protection for increased system
reliability, without the need for external sensing components. Key Features
