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.
