MC33063ADR TEXAS INSTRUMENTS IC
The MC33063A and MC34063A 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 PWMcontroller 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.
