Diodes Incorporated

AP4313

CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER

Description

Pin Assignments

The AP4313 is

a highly integrated solution for a constant

voltage/constant current mode SMPS application.

(Top View)

Pin 1 Mark

The AP4313 contains one 1.21V voltage reference with 1%

accuracy, one current sensing circuit and two operational amplifiers.

Combining the voltage reference with one operational amplifier makes

AP4313 an ideal voltage controller for use in adapters and battery

chargers. The other low voltage reference combined with the other

operational amplifier makes it an ideal current limiter for output low

side current sensing.
