3 Description
The MC33063A and MC34063A devices are easy-touse ICs containing all the primary circuitry needed for building simple DC-DC converters. These devices primarily consist of an internal temperaturepensated reference, a parator, an oscillator, a PWM controller with active current limiting, a driver, and a high-current output switch. Thus, the devices require minimal external ponents 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...
