Features and Applications

This Buck Boost Inverting Switching Regulator consists of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. New features include an internal thermal shutdown protection and cycle-by-cycle current limit. This series was specifically designed to be incorporated in step-down (buck) and step-up (boost) and voltage-inverting applications with a minimum number of external components. The NCV3063 is available for automotive applications.

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
