DC–to–DC CONVERTER  
CONTROL CIRCUITS  
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.
