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.
