... 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− ...

... A representative block diagram is shown in Figure 2. Operating Description The NCP3063 is a hysteric, dc−dc converter that uses a gated oscillator to regulate output voltage. In general, this mode of operation is somewhat analogous to a capacitor charge pump and does not require dominant pole loop compensation for converter stability ...
