CMOS-Compatible SOI MESFETS for Radiation-Hardened DC-to-DC Converters
- Created on Friday, 01 February 2013
A radiation-tolerant transistor switch has been developed that can operate between –196 and +150 °C for DC-to-DC power conversion applications. A prototype buck regulator component was demonstrated to be performing well after a total ionizing dose of 300 krad(Si). The prototype buck converters showed good efficiencies at ultra-high switching speeds in the range of 1 to 10 MHz. Such high switching frequency will enable smaller, lighter buck converters to be developed as part of the next project. Switching regulators are widely used in commercial applications including portable consumer electronics.This work was done by Trevor Thornton of Arizona State University and William Lepkowski and Seth Wilk of SJT Micropower for Goddard Space Flight Center.
