Typical Buck Application Schematic with External Low VCE(sat) PNP Transistor for NCV3063 1.5A Step-Down Switching Regulator

Typical Buck Application Schematic with External Low VCE(sat) PNP Transistor for NCV3063 1.5A Step-Down Switching Regulator. 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
