Part Number: TPS2378EVM-602 Other Parts Discussed in Thread: TPS23730 Can i power up my TPS2378EVM-602 board from non cisco poe++ switch?
Or i need only cisco switches for powering the board.
Part Number: TPS2378EVM-602 Other Parts Discussed in Thread: TPS23731EVM-095 , TPS2378 Hi Experts,
When i was reading the user guide of TPS2378EVM-602.
I found that the mosfet is not at output trace.
what is the difference between them.
Normally…

My customer did a quick test with the TPS2378EVM-602, by connecting the evaluation board to their system with PSE functions. They worked…
Part Number: TPS2378EVM-602 Hi,
I tried to get the board up and running, but after cabeling to the PSE, there was simply no measurable voltage on the output. The test with the Oszi on the TP3 also showed no start of the switch.
Am I doing something…
Hi Tiger,
In general the TPS2373-3 is recommended for isolated 51W designs whereas the TPS2372-3 is recommended for non-isolated 51W designs. However, if wanting to use the TPS2372-3 in an isolated design for 51W/19V, I recommend using the TPS2372-3…
Hi Michael,
Thanks for your reply.
Other issues are as follows:
1. Whether TPS2373-4 (IEEE 802.3bt) can use 100uF and work normally? (Below schematic is part of TPS2373-4EVM-758 SCH)
2. I tried EC7 with 47uF, sometimes the PSE reconnects more…
Hi, John, thank you. I'll try it, but can you explain why it needed to disconnect AUX when in reference design (TPS2378EVM-602 Evaluation Module) AUX connected the same way? Difference between these designes only in POE transformer (19V to 12V) and values…
Hi Chentsu,
I have not tested with a Cisco UPOE switch particularly; however I know of many projects that use this design in forced UPOE application with no issues. I recommend ordering a TPS2378EVM-602 and testing with a forced UPOE switch to verify…
Hi Howard,
In your system, you need a dual signature PD which have two PD controller for each PSE channel.
If you use software to control 4-pair ports, you can use a single signature PD which only has one PD controller. But you can't implement detect…
Hi User, In order to successfully detect & classify on the 2nd port, the RTN pins cannot be connected together because the diode bridge of the 2nd port will be reverse biased. See TPS2378EVM-602& the associated non-standard forced 4-pair app note, slva625a…
