AP4301BP-D

Data Sheet DUAL OP AMP AND VOLTAGE REFERENCE General Description The AP4301 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 corresponding reduction in system complexity and cost. The AP4301 is available in standard packages of DIP8 and SOIC-8.
