ABSTRACT:
In a power supply system for a passive safety device, a step-up circuit steps up an input voltage based on a supply voltage from a battery to obtain a predetermined output voltage. An input voltage detecting circuit detects the input voltage. An output voltage changing circuit changes the output voltage based on a detection signal from the input voltage detecting circuit. Thus, the control load on the step-up circuit is reduced and increase in the size and rating of the step-up circuit is suppressed.
