Abstract
A power supply having a primary side and a secondary side is disclosed. The power supply includes a main transformer having a first side and a second side. The first side is coupled to the primary side and the second side coupled to the secondary side. The power supply further includes a primary switch coupled to the first side and a synchronous rectification switch coupled to the second side. A controller is included for driving the primary switch and the synchronous rectification switch in several operation modes including the operation in continuous conduction mode. The controller is configured to determine and set a time between turning-off of the synchronous rectification switch and turning-on of the primary switch based on sampling of the peak voltage at the drain of the synchronous rectification switch and selecting the time that corresponds with the lowest peak voltage on the drain of the synchronous rectification switch.
