ADP5022ACBZ-4-R7 Description
The ADP5022ACBZ-4-R7 is a micro power management unit (micro PMU) that combines two high-performance buck regulators and a low dropout regulator (LDO) in a tiny 16-ball 2.08 mm x 2.08 mm WLCSP to meet demanding performance and board space requirements. The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space required. When the MODE pin is set high, the buck regulators operate in forced PWM mode. When the MODE pin is set low, the buck regulators automatically switch operating modes, depending on the load current level.
