Description
The MC34063A/MC33063A is a monolithic regulator sub
system intended for use as DC to DC converter. This 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 regulators as well as for series pass regulators.
