MC33063 IC – Buck – Boost – Inverting Switching Regulator IC

The MC33063A devices are easy-to-use ICs containing all the primary circuitry needed for building simple DC-DC converters. These devices primarily consist of an internal temperature-compensated reference, a comparator, an oscillator, a PWM controller with active current limiting, a driver, and a high-current output switch. Thus, the devices require minimal external components to build converters in the boost, buck, and inverting topologies. The MC33063A device is characterized for operation from ?40?C to 85?C.
