ACT4523A Overview
ACT4523A 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. ACT4523A provides up to 3.5A output current at 250kHz switching frequency. Active CC is a patented control scheme to achieve highest accuracy with sensorless constant current control.
