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

Benefits:

• 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

Applications:

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

End Products:

• Multi-Function Printers (MPF)
