General Description

The NCS1002 is a highly integrated solution for Switching Mode Power Supply (SMPS) applications requiring a dual control loop to perform Constant Voltage (CV) and Constant Current (CC) regulation.

The NCS1002 integrates a 2.5 V voltage reference and two precision op amps.

The voltage reference, along with Op Amp 1, is the core of the voltage control-loop.

Key Features

  • Low Input Offset Voltage: 0.5 mV, Typ.
  • Input Common-Mode Range includes Ground.
  • Low Quiescent Current: 300 mA per Op Amp at VCC = 5 V.
  • Large Output Voltage Swing.
  • Wide Power Supply Range: 3 V to 32 V.
  • High ESD Protection: 2 kV.
  • These are Pb.
  • Free Devices Typical.
