Description

The DA9122 is a Sub-PMIC suitable for supplying CPUs, GPUs, and DDR memory rails in smartphones, tablets, RF modules, and other handheld applications.

DA9122 integrates two single-phase buck converters, each phase requiring a small external 0.10μH inductor. It is capable of delivering up to 5A output current at a 0.3V to 1.9V output voltage range. The 2.5V to 5.5V input voltage range is suitable for a wide variety of low-voltage systems, including, but not limited to, all Li-ion battery-supplied applications.

Benefits

Input voltage range provides flexibility to run from single-cell Li-ion battery or standard 3.3V or 5V system rail
Differential voltage sensing provides tight regulation accuracy requirements of CPU cores in mobile SoCs
4MHz switching frequency reduces the footprint and height of the output inductor and minimizes output capacitance, lowering BOM cost
Triggered through either an I²C or GPIO interface, output dynamic voltage control can be used to optimize system power consumption
