GENERAL DESCRIPTION
ACT4523 is a wide input voltage, high efficiency Active CC step-down DC/DC converter that
operates in either CV (C***tant Output Voltage) mode or CC (C***tant Output Current) mode.
ACT4523 provides up to 3A output current at 225kHz switching tive CC is a patent-pending control scheme to achieve highest accuracy sensorless c***tant current control. Active CC eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applicati*** and adaptors with accurate current limit. The ACT4523 achieves higher efficiency than traditional c***tant current switching regulators by eliminating its associated power loss. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency foldback at short circuit. The devices are ***ailable in a SOP-8EP
package and require very few external devices for operation.
