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 lowvoltage 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.
