ACT4528 Overview
ACT4528 is a wide input voltage, high efficiency step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. ACT4528 has QC2.0 decoding built in to provide 5.1V/9.1V/12.1V outputs as requested by attached portable devices. It also supports Apple 2.4A, Samsung and BC1.2 devices to charge at full current rate.
