Proton radiation test of DC/DC converter with high voltage output

Radiation hardness of the COTS high voltage DC-DC converter was tested up to 90 krad(Si) using proton beams. Total dose effects with subsequent annealing were determined. Dependence on operating conditions and dose rate was observed. Mainly responsible parts were identified and functional failure of the device was attributed to the input current increase driven by power MOSFET.
