Abstract
A load control device includes a switching unit which is connected to a power source and a load in series and has a switch device having a transistor structure, a control unit configured to control start-up and stop of the load, and a gate driving unit, which is electrically insulated from the control unit and outputs a gate driving signal to the gate electrode of the switch device. The control unit controls the gate driving unit to supply a higher driving power to the gate electrode of the switch device for a predetermined period of time starting at the start-up of the load than that in a steady state.
