Radiation Effects on a Small DC-DC Converter and a Remedy by Circuit Design Technique

Abstract

This report presents the complete results of the total-dose and dose-rate testing on a typical-high-efficiency, low-power, low-voltage DC-DC converter used in commercial portable devices. The purpose of these investigations was to characterize performance of the converter in radiation environment at high and low dose rates. Results of the test include time-domain performance and frequency response before and after the irradiation. The converter maintained regulation control at 100 krads; however, the output voltage regulation drifted-up. Adding an external standby output-voltage regulating circuit has successfully solved the problem.
