General Description

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 OpAmps 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 Amp2 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-reduction in system complexity and cost.The AP4310 is available in standard packages of DIP-8 and SOIC-8.
