DESCRIPTION/ORDERING INFORMATION  
The MC33063A and MC34063A are easy-to-use ICs containing all the primary circuitry needed for building  
simple dc-dc converters. These devices primarily consist of an internal temperature-compensated reference, a  
comparator, an oscillator, a PWM controller with active current limiting, a driver, and a high-current output switch.  
Thus, the devices require minimal external components to build converters in the boost, buck, and inverting  
topologies.  
The MC33063A is characterized for operation from –40°C to 85°C, while the MC34063A is characterized for  
operation from 0°C to 70°C.
