When a flyback transformer T1 and a metal oxide semiconductor field effect transistor (hereinafter referred to as MOSFET) Q2 serving as a switching element are turned on, energy is accumulated in the magnetization inductance of the flyback transformer T1 Conversely, when the MOSFET Q2 is turned off, the stored energy is transferred to the secondary side of the flyback transformer T1. At this time, the voltage is applied to the primary side and the secondary side of the flyback transformer T1 And the output voltage is varied by the pulse width control duty ratio of the MOSFET Q2 controlling on / off of the flyback transformer T1.
