ACT4533AYH-T Overview
ACT4533A/B 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. ACT4533A/B provides up to 3.5 A output current at 125 kHz switching frequency. ActiveCC is a patented control scheme to achieve highaccuracy sensorless constant current control.
