<p><P>PROBLEM TO BE SOLVED: To provide a switching circuit that has a reduced amplitude of noise due to the operation of a switching element, is reduced in size, and is manufactured in a low cost. <P>SOLUTION: A switching circuit includes a switching element, a driver-signal output circuit that outputs a driver signal of a pulse wave at a constant period, and a driving circuit that drives the switching element in synchronization with the period of the driver signal while changing a driving force in a constant period including a plurality of periods of the pulse wave of the driver signal. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
