MC34063DC-DC Switching Power Supplies

General Description 

The MC34063 series is a monolithic control circuit containing primary functions required for DC-to-DC converters. These devices consist of an internal temperature-compensated reference, comparator, controlled duty cycle oscillator withan active current limit circuit, driver and high current output switch. This series was specifically designed to be incorporated in step-down and step-up and voltage-inverting applications with a minimum number of external components.

Features
