摘　　要：利用脉冲激光源,对一种采用0.35μm BiCMOS工艺PWM控制器作为控制核心的DC/DC变换器的瞬时电离剂量率效应进行研究。采用光斑直径为10 mm、波长为1064 nm、脉宽为10 ns、能量从3μJ到2400μJ的激光对DC/DC变换器进行照射试验,监测DC/DC变换器在不同能量激光下的响应,并与脉冲γ射线的试验结果进行对比分析。试验结果表明,该DC/DC变换器在能量3μJ到577μJ激光照射下输出扰动时间约为4.3 ms,输出闭锁阈值在1031μJ左右。The transient dose rate effect of the DC/DC converter based on PWM controller with feature of 0.35μm was studied under pulsed laser.The DC/DC converter was irradiated by a laser with spot diameter of 10 mm,wavelength of 1064 nm,pulse width of 10 ns and energy from 3μJ to 2400μJ.The responses of DC/DC converter under different energy laser were monitored and compared with the experimental results of pulsedγ-ray.The experimental results show that the output disturbance time of DC/DC converter is about 4.3 ms under the 3μJ to 577μJ laser and the output locking threshold of DC/DC converter is about 1031μJ.
