1 AP4310E Document number: DS36787 Rev. 3 - 2 1 of 9 September 2014 Diodes Incorporated AP4310E A Product Line of Diodes Incorporated DUAL OP AMP AND VOLTAGE REFERENCE Description The AP4310E 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 precision shunt voltage reference. Op Amp 1 is designed for voltage control with its non-inverting 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.

2 AP4310E has more stringent reference voltage tolerance and offset. The AP4310E is available in standard package of SO-8.
