AP4300 Datasheet | BCD Semiconductor

Description 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 unmitted. The IC offers the power converter designer a control solution that features increased precision with a corresponding reduction in system plexity and cost. The AP4300 is available in standard packages of DIP8 and SOIC-8.
