AP4313 - BCD Semiconductor

AP4313 CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER

The AP4313 is a highly integrated solution for a constant voltage/constant current mode SMPS application. The AP4313 contains one 1.21V voltage reference with ±1% accuracy, one current sensing circuit and two operational amplifiers. Combining the voltage reference with one operational amplifier makes AP4313 an ideal voltage controller for use in adapters and.
