Datasheet AP4310A (Diodes)

A Product Line of Diodes Incorporated AP4310A DUAL OP AMP AND VOLTAGE REFERENCE Description Pin Assignments
The AP4310A is a monolithic IC specifically designed to regulate the output current and voltage levels of switching battery chargers and power supplies
(Top View)
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 OUTPUT 1 1 8 VCC regulator. Op Amp 2 is for current control with both inputs uncommitted. The IC offers the power converter designer a control INPUT 1- 2 7 OUTPUT 2 solution that features increased precision with a corresponding reduction in system complexity and cost. INPUT 1+/VKA 3 6 INPUT 2- The AP4310A is available in SO-8 package. GND 4 5 INPUT 2+
