MC34063A Series Monolithic Control Circuit
A compact powerhouse for DC-to-DC converters
The MC34063A Series is a monolithic control circuit containing the primary functions required for DC?to?DC converters. These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an 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.
