ADP5033ACBZ-5-R7 Description
The ADP5033ACBZ-5-R7 combines two high-performance buck regulators and two low dropout regulators (LDO) in a tiny, 16-ball, 2 mm×2 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. 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 operate in PWM mode when the load current is above a predefined threshold. When the load current falls below a predefined threshold, the regulator ADP5033ACBZ-5-R7 operates in power save mode (PSM), improving the light load efficiency.
