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 ...

Maximizing energy efficiency and power density have now become requirements for power supply designs in low power chargers and adapters. It has become necessary for synchronous rectification (SR) to ...

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 ...

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 ...

Marotta Controls today announced the award of U.S. Patent No. 12,283,877 for a novel synchronous rectification technique developed by Joseph Youssef, Marotta’s Senior Director, Electrical Engineering.

Due to continuous demand for high power density, USB-C fast chargers’ switching frequencies need to be increased to reduce the size of the transformers and the filter components. Emerging technologies ...
