We see from your search that you're looking for information on the term "Synchronous rectification",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Small DC/DC convertor suits tight applications from
Ideal Power, which we summarised at the time by saying "The open-frame EST series has a footprint of less than 774mm2, making it suitable for use in a range of networking, telecom, wireless and industrial designs requiring tight board spacing".
Earlier in the week,
we featured the news release Convertors boost single cells to 5.25V from
Linear Technology Corp: "Current-mode synchronous boost DC/DC convertors feature output disconnect and integrated soft-start capability".
In December 2007, we covered the news from Linear Technology Corp
concerning its LTC4268-1
- take a look at PoE controller powers up hungry devices
which says: "Power over Ethernet interface controller integrates a synchronous current-mode switching regulator for delivering precise regulation and high efficiency".
Take a look also at the news release from Vishay Siliconix, MOSFET and diode on one chip boost efficiency,
as well as Brick drops in to boost basestation efficiency from Ericsson Power Modules,
and Reduced resistance cuts load switching losses from Vishay Siliconix.
