Active-Semi ACT4515
ACT4515 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. The ACT4515 achieves higher efficiency than traditional constant current switching regulators by eliminating the sense resistor and its associated power loss. ACT4515 provides up to 1.5A output current at 210kHz switching frequency.| Part No. | ACT4515 |
