DA9122中文资料Configurable, Dual-Output 5A + 5A Sub-PMIC for High-Performance Mobile Processors and Memory数据手册Renesas规格书

描述 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.

BenefitsInput 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 SoCs4MHz switching frequency reduces footprint and height of output inductor and minimizes output capacitance, lowering BOM costTriggered through either an I2C or GPIO interface, output dynamic voltage control can be used to optimize system power consumption
