CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER
Description
The AP4320 is a highly integrated solution for a constant voltage/constant current mode SMPS application.
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.
The AP4320 is available in SOT26 package.
