PROBLEM TO BE SOLVED: To provide a load driver that drives, as needed, various lamps in a vehicle carrying a high-voltage power supply and allows the safe installation of vehicle lighting lamps and the like. SOLUTION: The load driver (1) is provided with a pulse converter (2) and a DC/DC converter (5). The pulse converter (2) can convert a high DC voltage outputted from the power supply (10) to a pulse voltage and applies the pulse voltage to a first lamp (L1). The DC/DC converter (5) converts a high DC voltage to a lower DC voltage and applies the low DC voltage to a second lamp (L2). COPYRIGHT: (C)2003,JPO
