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 2.5V 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. AP4310E has more stringent reference voltage tolerance and offset.
 
The AP4310E is available in standard package of SO-8.
