  • Sychronous Rectification
    Synchronous rectification (SR) is used in DC/DC converters when low output voltage is less than 5V and high current is needed. Synchronous rectification utilizes power MOSFETs to rectify the output voltage of the power transformer. These MOSFETs are synchronized to the converter frequency
