1 / 16 page © Semiconductor Components Industries, LLC, 2006 November, 2006 − Rev. 1 1 Publication Order Number: NCP3063/D NCP3063, NCP3063B, NCV3063 1.5 A, Step−Up/Down/ Inverting Switching Regulators 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. 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 Figure 1.
