DUAL OP AMP AND VOLTAGE REFERENCE AP4310/A

Jan. 2013 Rev. 1. 8 BCD Semiconductor Manufacturing Limited

Data Sheet

General Description

The AP4310/A is a monolithic IC specifically

designed to regulate the output current and voltage lev-

els of switching battery chargers and power supplies.

The device contains two Op Amps and a 2.5V preci-

sion shunt voltage reference. Op Amp 1 is designed for

voltage control with its non-inverting input internally

connected to the output of the shunt regulator. Op

Amp 2 is for current control with both inputs uncom-

mitted. The IC offers the power converter designer a

control solution that features increased precision with a

corresponding reduction in system complexity and

cost. AP4310A has more strigent reference voltage

tolerance than AP4310.

The AP4310/A is available in standard packages of

DIP-8 and SOIC-8.
