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. Refer to Application Notes AN920A/D and AN954/D

for additional design information.
