ACT4533C Overview
ACT4533C is a wide input voltage, high efficiency ActiveCC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. ACT4533C provides up to 3.5A output current at 125kHz switching frequency. ActiveCC is a patented control scheme to achieve high-accuracy sensorless constant current control.
