Insulated synchronous rectification DC/DC converter
A synchronous rectification controller is arranged on the secondary side of an insulated synchronous rectification DC/DC converter. The synchronous rectification controller controls a synchronous rectification transistor M. An automatic shutdown circuit judges, based on the voltage VDS across the synchronous rectification transistor, whether the operation mode of a primary-side controller is a burst mode or a non-burst mode. When judgment has been made that the operation mode is the burst mode, the automatic shutdown circuit instructs a driver to suspend the switching of the synchronous rectification transistor M.
