ACT4515全新原装现货13724201506李生。***:T4515 is a wide input voltage, high efficiency ActiveCC step-down DC/DC converter that operates in either CV (C***tant Output Voltage) mode or CC (C***tant Output Current) mode. ACT4515 provides up to 1.5A output current at 200kHz switching frequency.
ActiveCC is a patent-pending control scheme to achieve highest accuracy sensorless c***tant current control. ActiveCC eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applicati*** and hi***rightness LED drive for architectural lighting. The ACT4515 achieves higher efficiency than traditional c***tant current switching regulators by eliminating the sense resistor and 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-8 package and require very few external devices for operation.
