AP4320BK6TR-G1

A Product Line of Diodes Incorporated AP4320 CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER Description Pin Assignments The AP4320 is a highly integrated solution for a constant voltage/constant current mode SMPS application. (Top View) The AP4320 contains one 2.5V voltage reference and two operational amplifiers. The 2.5V voltage reference, combined with one operational amplifier, makes of an ideal voltage controller for use in adapters and battery chargers. The low voltage reference, combined with another operational amplifier, makes of an ideal current limiter for output low side current sensing. Pin 1 Mark VSENSE 1 6 VCC GND 2 5 VOUT VCTRL 3 4 ICTRL The AP4320 is available in SOT26 package.
