A Product Line of Diodes Incorporated AP4313 CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER Description Pin Assignments The AP4313 is a highly integrated solution for a constant voltage/constant current mode SMPS application. (Top View) Pin 1 Mark 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 battery chargers. The other low voltage reference combined with the other operational amplifier makes it an ideal current limiter for output low side current sensing. The AP4313 is available in SOT26 package.
