ACT4513 Overview
ACT4513 is a wide input voltage, high efficiency Active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. ACT4513 provides up to 2A output current at 210kHz switching frequency. Active CC is a patent-pending control scheme to achieve highest accuracy sensorless constant current control.
