AP4310A

DUAL OP AMP AND VOLTAGE REFERENCE

Description

Pin Assignments

The AP4310A is a monolithic IC specifically designed to regulate the

output current and voltage levels of switching battery chargers and

power supplies

(Top View)

The device contains two Op Amps and a 2.5V precision shunt voltage

reference. Op Amp 1 is designed for voltage control with its non-

inverting input internally connected to the output of the shunt

OUTPUT 1

VCC

regulator. Op Amp

2 is for current control with both inputs

uncommitted. The IC offers the power converter designer a control

solution that features increased precision with a corresponding

reduction in system complexity and cost.
