AP4301 General Description


The AP4301 is a monolithic IC specifically designed to control the output current and voltage levels of switch mode battery chargers and power supplies.

The device contains two operational amplifiers and a precision shunt regulator. OPAMP 1 is designed for voltage control, whose non-inverting input internally connects to the ouput of the shunt regulator. OPAMP 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.
