摘要
The total ionization dose effect of the integrated DC-DC power converter was studied under different conditions of different load currents, different input voltages, different dose rates and shutdown mode conditions. The experiment adopted online testing and in-situ testing methods. Before and after the irradiation and during the irradiation, the key parameters of the DC-DC power converters were tested and analyzed. The experimental results show that under the condition of large load current, the degradation of the output voltage is more significant, and the degree of degradation is more serious. A detailed explanation is provided for this phenomenon. The input current, as an important sensitive parameter under shutdown mode conditions, can be used to evaluate the reliability of the device. In addition, due to the annealing effect, the degradation degree of the output voltage at a low dose rate is less than that at a high dose rate. Therefore, the choice of rate is very important when analyzing and evaluating the total ionization dose effect of DC-DC power converters.
