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, thus reducing the ...

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 ...

The flyback is a popular topology for low and medium power AC-DC converters, mainly because of its low cost and ease of use. The flyback assumes a DC input, and includes a transformer, a power switch ...

Rfb is shown in Figure 2. 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 ...

The LT8309 from Linear Technology Corporation is a flyback secondary-side synchronous rectifier driver that replaces the output diode with a MOSFET, allowing up to 10 A output current without the ...
