The DA9220 is a sub-PMIC suitable for supplying CPUs, GPUs, and DDR memory rails in smartphones, tablets, RF modules, and other handheld applications. DA9220 integrates two single-phase buck converters, each phase requiring a small external 0.10μH inductor. It is capable of delivering up to 3A of 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 a 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 (DVC) can be used to optimize system power consumption
