LTspice SOAtherm Support for PCB and Heat Sink Thermal Models

Dan Eddleman - Senior Applications Engineer Sep 1st 2016
The SOAtherm model distributed with LTspice software and simplifies Hot Swap and Surge Stopper designs by verifying directly within a circuit simulation that a particular MOSFET’s Safe Operating Area (SOA) is not exceeded. This article assumes a basic understanding of the SOAtherm model. If you are not familiar with SOAtherm, ...

LT4321/LT4275 LTPoE++/PoE+/PoE PD Controller TechClips

Oct 24th 2013
Power over ethernet is a continuing trend in the Ethernet world. The current IEEE standard allows for up to 25.5W of PD input power. LTPoE++ is Linear Technology's solution to meet the demand for greater power with 38.7W, 52.7W, 70W and 90W power levels. Heat generated by Power Over Ethernet powered device (PD) ...

Active Bridge Rectifiers Reduce Heat Dissipation within PoE Security Cameras

Ryan Huff - PoE Applications Engineer Oct 1st 2013
Introduction Power over Ethernet (PoE) has been embraced by the video surveillance industry as a solution to an age-old problem: complicated cabling. For instance, a basic, traditional fixed-view security camera requires two cables: one for power (10W to 15W from a 24V AC or 12V DC), and a separate, coax cable for the video ...
