Patent ID: 7635970

Claim:
A buck converter for producing relatively low output voltages comprising: input means for inputting an input voltage; two P channel FETS including a first P-channel FET and a second P-channel FET; switching means for switching conductively between the first P-channel FET and the second P-channel FET, said switching means includes pulse modulation means for turning off one of said two P-channel FETS before turning on another of said two P channel FETs so as to avoid simultaneous conduction of said two P-channel FETs; and output means for outputting an output voltage, said output voltage being a step-down voltage, whereby the output voltage is lower than the input voltage; and wherein the first P-channel FET, second P-channel FET and the output voltage are unaffected by high-ionizing radiation such that is found in space or particle accelerators.
