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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
