DA9121

High-Performance, 10 A,

Dual-Phase DC-DC Converter

General Description

DA9121 is a power management unit (PMU) suitable for supplying CPUs, GPUs, DDR memory rails

in single in-line pin package (SIPP) modules, smartphones, tablets, and other handheld applications.

DA9121 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 low-

voltage systems, including, but not limited to, all Li-Ion battery supplied applications.

With remote sensing, the DA9121 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 DA9121 in the

same application.

DA9121 has integrated over-temperature and over-current protection for increased system reliability,

without the need for external sensing components.
