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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. PRODUCTION DATA information is current as of publication date. Copyright © 2004–2009, Texas Instruments Incorporated Products conform to specifications per the terms of the Texas Instruments standard warranty.
