General Description

The AP4302 is a monolithic IC specifically designed to regulate the output current and voltage levels of switching battery chargers and power supplies. The device contains quad Op Amps and a 2.5V externally adjusted voltage reference in a 16-pin package. The four Op Amps feature accurate voltage and current control. Combining a stable voltage reference with the four Op Amps makes AP4302 ideal for use in multi function charger, power supply voltage monitor, signal processing and control system. The IC offers the power converter designer a control solution that features increased precision with a corresponding reduction in system complexity and cost. The AP4302 is available in standard packages of DIP-16 and SOIC-16.
