Power supply designers are all too familiar with the fact that the power switches are among the key contributors to overall power loss. For high current applications, this is the reason lower losses ...

Synchronous rectifiers are MOSFETs, driven in such a way as to perform a rectifying function. They often take the place of diodes in the output-rectification stage of switching power converters, ...

Many of today’s switching power supplies implement synchronous rectifiers to improve efficiency. In isolated topologies, the power-supply controller typically is located on the primary side of the ...

The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of flyback converters increases with each new generation of MOSFETs, improving performance at little or no ...

ST has introduced a pair of autonomous secondary-side synchronous-rectification controllers for fly-back converters, suitable for quasi-resonant and continuous-discontinuous conduction fixed frequency ...
