... NCP3163, NCV3163 3.4 A, Step−Up/Down/ Inverting 50−300 kHz Switching Regulator The NCP3163 Series is a performance enhancement to the popular MC33163 and MC34163 monolithic DC−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 controller was specifically designed to be incorporated in step− ...
