LTC3723-1 130W Isolated Push-Pull Converter for PoE Applications with 93.5% Peak Efficiency

Jeoffrey (Zijian) Wang - Applications Engineer Oct 3rd 2016
This solution is a non-synchronous isolated push-pull converter designed for PoE applications, which can generate a 50V/2.6A output from a 34-38V (36V typical) input voltage range. A 93.5% peak efficiency is achieved for the whole isolated converter and the total solution can be fit into 1/8 brick footprint (2.3” x 0.9”) ...

LTC4226 Parallel MOSFETs in Hot Swap Circuits

Dan Eddleman - Senior Applications Engineer
Gabino Alonso - Strategic Marketing Engineer
Mar 13th 2015
The Good, the Bad, and the Ugly Introduction While it is often desirable, and sometimes absolutely critical, to use multiple parallel MOSFETs in Hot Swap™ circuits, careful analysis of Safe Operating Area (SOA) is essential. Each additional parallel MOSFET added to a circuit improves the voltage drop, power loss, and ...
