| Data Sheet DUAL OP AMP AND VOLTAGE REFERENCE General Description The AP4300 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 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 corresponding reduction in system complexity and cost. The AP4300 is available in standard packages of DIP8 and SOIC-8. AP4300 Features Op Amp * Input Offset Voltage: 0.5mV * Supply Current: 250A per Op Amp at 5.0V Supply Voltage * Unity Gain Bandwidth: 1MHz * Output Voltage Swing: 0 to (VCC - 1.5) V * Power Supply Range: 3 to 18V Voltage Reference * Fixed Output Voltage Reference: 2.5V, 2.6V * Voltage Tolerance: 0.5%, 1% * Sink Current Capability from 0.1 to 80mA Applications * * Battery Charger Switching Power Supply SOIC-8 DIP-8 Figure 1.
