Features and Applications

The NCP3063 Series is a higher frequency upgrade to the popular MC34063A and MC33063A monolithic DC−DC converters. These devices consist of an internal temperature compensated reference,comparator, a controlled duty cycle oscillator with an active current limit circuit, a driver and a high current output switch. This series was specifically designed to be incorporated in Step−Down, Step−Up and Voltage−Inverting applications with a minimum number of external components.

Key Features:

  • Operation to 40 V Input
  • Low Standby Current
  • Output Switch Current to 1.5 A
  • Output Voltage Adjustable
  • Frequency Operation of 150 kHz
  • Precision 1.5% Reference
  • New Features: Internal Thermal Shutdown with Hysteresis
  • New Features: Cycle−by−Cycle Current Limiting
  • Pb−Free Packages are Available


  • Flexibility to operate over a wide range of applications
  • Reduced output capacitance and ability to use SMT inductor
  • This feature is provided to prevent catastrophic failures from accidental device overheating
  • Improved protection capability over MC34063
  • Calculate support components and estimate performance


  • Step−Down, Step−Up and Inverting supply applications
  • High Power LED Lighting
  • Battery Chargers

End Products:

  • Multi-Function Printers (MPF)
