Semiconductor Components Industries, LLC, 2016 December, 2016 Rev. 241 Publication Order Number: mc34063a /DMC34063A, MC33063A, sc34063a , sc33063a , A, Step-Up /Down/ inverting SwitchingRegulatorsThe mc34063a Series is a monolithic control circuit containing theprimary functions required for DC to DC converters. These devicesconsist of an internal temperature compensated reference, comparator,controlled duty cycle oscillator with an active current limit circuit,driver and high current output switch. This series was specificallydesigned to be incorporated in Step Down and Step Up andVoltage inverting applications with a minimum number of externalcomponents. Refer to Application Notes AN920A/D and AN954/Dfor additional design Operation from V to 40 V Input Low Standby Current Current Limiting Output Switch Current to A Output Voltage Adjustable Frequency Operation to 100 kHz Precision 2% Reference NCV Prefix for Automotive and Other Applications RequiringUnique Site and Control Change Requirements; AEC Q100 Qualified and PPAP Capable These Devices are Pb Free, Halogen Free/BFR Free and are RoHSCompliantFigure 1.
