Features and benefits

  • Stabilized output current of 10 mA without external resistor
  • Stabilized output current adjustable up to 150 mA when an external resistor is used
  • High current accuracy at supply voltage variation
  • Low voltage overhead of 1.4 V
  • Reduces component count and board space
  • High power dissipation of 750 mW
  • Supply voltage up to 40 V
  • Digital PWM input up to 10 kHz frequency for NCR421U
  • AEC-Q101 qualified

Applications

  • Constant LED driver
  • Generic constant current source
  • Automotive applications (for example: interior lighting, dash board, instrumentation, number plate light)
  • Increase stabilized output current by paralleling drivers
