Part Number: TPS23861 Hi Sir
I have few questions about PSE + PD user case,
1) In i2C mode, an PSE is setting to about 15W, PD still keep to 25.5W output, if we those two POE connection, the output is limiting to 15W only? or output raising to 25…
Hi Mauricio,
Here's my comment:
Current solutions for 802.af(PoE), 802.3at(PoE+), LTPoE++:
802.af: PSE: TPS23861 PD:Front End only:LM5073,TPS2376-H,TPS2375/7-1,TPS2375/7; Front End+DCDC:TPS23757,TPS23753A,TPS23750/70,LM5070/1

Part Number: TPS23753A Other Parts Discussed in Thread: PMP11107 , Tool/software: Hi,
I need to use the PMP11107 reference design that uses the TPS23753A with dual output, which includes a transformer as shown here: www.ti.com/.../PMP11107.
However…
Other Parts Discussed in Thread: TPS23754 Hi,
1. POE have 2-Event classification and LLDP negotiation, i want to confirm 802.3at standard have support one or both?
2. How to implement DLL negotiation in TPS23754?
Thanks.
ORing issues and some considerations are also discussed at a high level in the TPS23753A datasheet and the TPS23754A datasheet. There are a few fundamental limitations that you might run into in trying to create a seamless switch, and in general they…
Other Parts Discussed in Thread: TPS23754 Hello,
In the table of Classes and Power of TPS23754 minimum power to PD in Class 4 is 12.95W.
The customer would like to get confirmation that if PD needs less power this also will work.
Pls advise.…
Take a look at TPS23754. It is a type 2 PD and dc/dc controller designed for 25W, 2 pair applications. The minimum current limit for the PASS FET is 850mA. For 45W, you would need 53V in at 850mA.
TI has a couple of high power reference designs using…
Other Parts Discussed in Thread: TPS23757 , TPS23754 , TPS23757EVM Hello,
I can't find TPS23757 active clamp forward topology for 5V/2A reference design in PowerLab,
I need transformer data and reference design, Anyone can provide for me?
Thanks…
Standard compliant (IEEE 802.3at) implementations do not envision paralleled PDs on one power feed. This is aligned to data handling.
Please see/read TPS23754 datasheet for some information in the applications section regarding how a type 2 system…
