High-Performance, 10 A, Dual-Phase DC-DC Converter
High-Performance, 10 A, Dual-Phase DC-DC
Converter General Description
DA9130 is a power management unit (PMU) suitable for supplying CPUs, GPUs, DDR memory rails
in switches and routers, smart metering, industrial automation, wireless applications, consumer
products, and SoC/FPGA high performance processing systems requiring efficient, high current,
DA9130 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 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 in the
DA9130 has integrated over-temperature and over-current protection for increased system reliability,
without the need for external sensing components. Key Features
