AP4320
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.
