ADP5034AREZ-R7 Description

The ADP5034AREZ-R7 combines two high-performance buck regulators and two low dropouts (LDO) regulators. It is available in either a 24-lead 4 mm × 4 mm LFCSP or a 28-lead TSSOP package. The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space. When the MODE pin is set to high, the buck regulators operate in forced PWM mode. When the MODE pin is set to low, the buck regulators operate in PWM mode when the load is above a predefined threshold. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM), improving the light load efficiency.
