Abstract
An input smoothing circuit is provided between an input line and a ground line. A high-side transistor and a low-side transistor are provided in series between the two ends of the input smoothing circuit. The high-side transistor and the low-side transistor are arranged side by side in a first direction on a circuit board. Two current loops that run through the smoothing circuit, the high-side transistor, and the low-side transistor are formed to be substantially linearly symmetrical with respect to an axis of symmetry that extends in the first direction.
