Data Sheet
DUAL OP AMP AND VOLTAGE REFERENCE
AP4301
General Description
Features
The AP4301 is a monolithic IC specifically designed
to regulate the output current and voltage levels of
switching battery chargers and power supplies.
Op Amp
· Input Offset Voltage: 0.5mV
· Supply Current: 250µA per Op-Amp at 5.0V Supply Voltage
· Unity Gain Bandwidth: 1MHz
· Output Voltage Swing: 0 to (VCC-1.5)V
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.
·
Power Supply Range: 3 to 18V
Voltage Reference
· Fixed Output Voltage Reference: 1.25V, 1.24V
· Voltage Tolerance: 0.5%, 1%
· Sink Current Capability from 0.1 to 80mA
The AP4301 is available in standard packages of DIP8 and SOIC-8.
