Fairchild Semiconductors
The MC34063A 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.
Features:
Operation from 3.0 to 40V input
Short circuit current limiting
Low standby current
Output switch current of 1.5A without external transistors
Adjustable output voltage
Frequency of operation from 100Hz to 100kHz
Step-up, step-down, or inverting regulators
