AP4310 Datasheet PDF - BCD Semiconductor

●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 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.

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