AP4312 - Diodes Incorporated

AP4312 CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER

The AP4312 is a highly integrated solution for a constant voltage/constant current mode SMPS application. The AP4312 contains one 1.21V voltage reference, one low voltage reference used in current sensing circuit and two operational amplifiers. The 1.21V voltage reference, combined with one operational amplifier, makes of an ideal voltage controller for use .
