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
