Description

The MC34063A/MC33063A is a monolithic regulator

subsystem intended for a DC to DC converter. The

device contains a temperature-compensated bandgap

reference, a duty cycle control oscillator, driver, and

high-current output switch. It can be used for step-

down, step-up, or inverting switching and series pass

regulators.
