Abstract
The irradiation response of a DC-DC power converter was studied. During the test, the characteristic parameter of DC-DC power converter such as input current and output voltage increased slowly with empty load, and DC-DC power converter was unsteady and the characteristic parameter was strongly influenced by the total-dose when fully loaded. It was indicated that failure of DC-DC converter was due to the source and drain of VDMOSFET fused together because of over power.
