The GM34063 has all the functions required for

DC-to-DC converters: an internal temperature-

compensated reference, comparator, controlled

duty cycle oscillator with an active current limit

circuit, driver, and high-current output switch.

The 34063 designed for step-down, step-up and

voltage-inverting applications using a minimum

number of external components.
