The MC33063DFBCKGEVB is a buck switching regulator evaluation board to evaluate MC33063A buck/boost/inverting switching regulator. The MC33063A is a monolithic control circuit containing the primary functions required for DC to DC converters. These buck/boost/inverting switching regulators consists of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. The MC33063A specifically designed to be incorporated in step down (buck), step up (boost) and voltage inverting applications with a minimum number of external components.
