DA9121 Overview
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.
