MC33063A - Texas Instruments

MC33063A 1.5-A Peak Boost/Buck/Inverting Switching Regulators

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 requir.
