AP4310AMTR-G1

AP4310AMTR-G1 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 precision shunt voltage reference. Op amp 1 is designed for voltage control with its noninverting input internally connected 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. Applications include battery charger and switching power supply.
