Abstract
A synchronous rectification control circuit includes a first drive unit that outputs a signal for controlling turning on/off of a synchronous rectification element disposed on a secondary side, a second drive unit that performs control to make a voltage between both ends of the synchronous rectification element equal to a predetermined threshold voltage during a predetermined period during which a rectification current flows on the secondary side, and a drive switching unit that selectively supplies an output from the first drive unit and an output from the second drive unit to the synchronous rectification element.
