AP4320

CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER

Description

Pin Assignments

The AP4320 is

a highly integrated solution for a constant

(Top View)

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.
