DUAL OP AMP AND VOLTAGE REFERENCE
General Description
Features
Data Sheet
AP4310
The AP4310 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 preci-
sion shunt voltage reference. Op Amp 1 is designed for
voltage control with its 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 AP4310 is available in standard packages of DIP-
8 and SOIC-8.
