3 Description

The MC33063A and MC34063A devices 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 device is characterized for operation

from –40°C to 85°C, while the MC34063A device is

characterized for operation from 0°C to 70°C.
