DUAL OP AMP AND VOLTAGE REFERENCE
General Description
Features
Data Sheet
AP4300
The AP4300 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 operational amplifiers and a
precision shunt regulator. Op Amp 1 is designed for
voltage control, whose non-inverting input internally
connects 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 corre-
sponding reduction in system complexity and cost.
The AP4300 is available in standard packages of DIP-
8 and SOIC-8.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Max-
imum Ratings" for extended periods may affect device reliability.
