Part Number: TPS2378
Hi, this is my first post here. I have some experience designing around Arduinos and ESP32's, but this is my first design with PoE and the TPS2378.
Basically, i've been told that jacks with CTs on the "board-side" are useless…
Part Number: TPS2378 Do you have a recent app note or white paper on how to do this? There was mention of a presentation here: https://www.ti.com/product/TPS2378?keyMatch=TPS2378&tisearch=search-everything&usecase=GPN-ALT Perhaps you can send me…
Part Number: TPS2378 Dear TI support,

Part Number: TPS2378 Hello
I use TPS2378 on our product, I measured output voltage at TPS2378 (between VDD and RTN pins) and inrush current between PSE (PoE injector) and our device. The ramp up time of the output voltage is very fast, I've measured typically…
