The device contains two Op Amps and a 2.5V precision shunt voltage reference. Op Amp 1 is designed for voltage control with its non-inverting input internally connected 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. AP1234 has more stringent reference voltage tolerance and offset.


  • Input Offset Voltage: 0.5mV
  • Supply Current: 75µA per OP Amp at 5.0V Supply Voltage
  • Unity Gain Bandwidth:1MHz
  • Output Voltage Swing: 0 to VCC -1.5V


  • Battery Charger
  • Switching Power Supply
