A DC-DC converter (4) for use as a power supply for a safety device for use in a vehicle. The DC-DC converter (4) incorporates a first converter circuit (6) and a second converter circuit (7). The converter circuits (6,7) share an inductor (L). The first converter circuit (6) is configured to output a first voltage (VHigh) which is higher than the input voltage (Vin) and, simultaneously, the second converter circuit (7) is configured to output a second voltage (VLow1) which is lower or higher than the input voltage (Vin). |
