General Description
The AP4300 is a monolithic IC specifically designed
to regulate the output current and voltage levels of
switchin g battery chargers and power supplies.
The device contains two operational amplifiers and a
precision shunt regulator. Op Amp 1 is designed for
voltage control, whose non-inverting input internally
connects 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 corre-
sponding reduction in system comp lexi ty and cost.
The AP4300 is available in standard packages of DIP-
8 and SOIC-8.
