In DCM, the flyback converter is a first-order system at low frequencies, which eases the feedback-loop compensation. You can use a low-cost secondary rectifier, thanks to soft blocking conditions. In ...

In this power tip, I’ll explore further to see the effects of parasitic inductance and how using synchronous rectifiers instead of diodes can greatly improve cross-regulation in flyback power supplies ...

The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of flyback converters increases with each new generation of MOSFETs, improving performance ...

With it, the output voltage can be adjusted. Nps is the turns ratio of the transformer used, and Vf is the voltage drop across the secondary-side flyback diode. This is usually quite temperature ...

Linear Technology’s LT3809 flyback secondary-side synchronous rectifier driver replaces the output diode forward-voltage drop with the RDS(ON) of an external N-channel MOSFET, ...

Zetex has announced a synchronous rectifier controller for flyback converters. Combined with a discrete power Mosfet, the ZXGD3101T8 ‘zero point detector driver’ replaces Schottky and other diodes to ...
