DUAL OP AMP AND VOLTAGE REFERENCE AP4310/A

General Description

The AP4310/A is a monolithic IC specifically
designed to regulate the output current and voltage lev­els of switching battery chargers and power supplies.

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. AP4310A has more strigent reference voltage
tolerance than AP4310.

The AP4310/A is available in standard packages of
DIP-8 and SOIC-8.
