Part Description

The MC33063A and MC34063A devices are easy-touse ICs containing all the primary circuitry needed for building simple DC-DC converters. These devices primarily consist of an internal temperaturecompensated 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, while the MC34063A device is characterized for operation from 0°C to 70°C.
