MC34063A, MC33063A  
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.
