Inverting Switching
RegulatorsThe 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 oltage−Inverting applications with a minimum number of external
components.
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
Applications Step−Down, Step−Up and Inverting supply applications High Power LED Lighting Battery Chargers
