AP4310E

DUAL OP AMP AND VOLTAGE REFERENCE

Description

The AP4310E is a monolithic IC specifically designed to regulate the

output current and voltage levels of switching battery chargers and

power supplies

Pin Assignments

(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

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. AP4310E has more

stringent reference voltage tolerance and offset.

The AP4310E is available in standard package of SO-8.
