Insulated synchronous rectification DC/DC converter including capacitor and auxiliary power supply
A first capacitor and an auxiliary power supply are provided to a secondary side of an insulated synchronous rectification DC/DC converter, in addition to a synchronous rectification transistor and a secondary-side controller. One end of the first capacitor is connected to a first node that connects the synchronous rectification transistor and a secondary winding. The auxiliary power supply charges the first capacitor using the voltage VOUT supplied via the output line, so as to stabilize the voltage across the first capacitor. The ground voltage is supplied to the secondary-side controller via the first node. Furthermore, the power supply voltage is supplied to the secondary-side controller via the other end of the first capacitor.
