Classification: H02M

Abstract:
1. A buck converter for producing relatively low output voltages comprising: a first P-channel FET; a second P-channel FET; switching means for switching conductivity between the first P-channel FET and the second P-channel FET; output means for outputting an output voltage, said output voltage being a step-down voltage; scaling means for scaling the output voltage to a nominal level; control means for controlling a current flow though said first and second P-channel FET; determining means for determining an output pulse width; soft-starting means for raising/lowering the output voltage at a controlled rate; monitoring means for monitoring an operating status of the converter; and disabling means for disabling the output voltage of the converter, wherein the first P-channel FET, second P-channel RET and the output voltage are unaffected by high-ionizing radiation such that is found in space or particle accelerators.
