Increasing demands for improvements in power supply efficiency means that traditional rectification using standard, ultrafast and Schottky diodes is gradually being replaced by elaborate schemes using ...

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 ...

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 power ...

Fig. 1: A conventional flyback topology experiences significant switching losses. Mladen Ivankovic is a Sr. Staff Application Engineer at Infineon A classic flyback converter stores energy as a ...

Diodes has announced the APR348, a secondary-side, multi-mode synchronous rectification mosfet driver. The driver is designed for AC-DC rectification circuits in general consumer applications, ...

Isolated outputs are required for a broad range of DC/DC converter applications — far beyond the well-known telecom and datacom mandated isolation requirements. Isolation can be necessary for noise ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...
