Product Summary

The MC34063ADR2G is a monolithic control circuit containing the primary functions required for DC–to–DC converters. It consists of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. The MC34063ADR2G was specifically designed to be incorporated in Step–Down and Step–Up and Voltage–Inverting applications with a minimum number of external components. Refer to Application Notes AN920A/D and AN954/D for additional design information.
