The MC34063A Series are switching regulators with monolithic control circuit containing the  primary functions required for DC−to−DC converters. These devices consist 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 specifically designed to be incorporated in Step−Down and Step−Up and Voltage−Inverting applications with a minimum number of external components. The MC33063 is an extended temperature version. The NCV33063 is an extended temp version for automotive.
