Part Number: TPS23756 Hi Team,
Customer is designing TPS23756 POE.
Can TPS23756 inform the system MCU the PSE connection is POE or POE+ via T2P?

Hi Harry,
I assume you are talking about TPS23756 instead of TPS23754.
TPS23756 has ~9V UVLO at VC. VC also has a max operation voltage (recommended operating conditions) as 18V. So it is needed to make VC 9 - 18V during operating. And normally 12 - 16…

Hi Team,
In this case, the schematic of TPS23756 is same as the TPS23756EVM schematic.
But we have problem to have an expected stable 5V/3A output.
We can find that Vout is unstable and the device is enter pulse skipping under zero…
Part Number: TPS23756 Hi Team,
May I have your help to teach my customer how to calculate Tj for TPS23756? (If it without power consumption)
Datasheet show we have tested it at 88C base on our condition but customer want to know how to test it withou…
Part Number: TPS23756 Dear Sir/Ms.
The customer confirmed that after the TPS23756 R_CLS was replaced with 1.5K ohm or 137 ohm, the Classification Current value would be the same as that in Datashhet. But after using 137 ohm set to Class 2, 13W power can…
Part Number: TPS23756 Other Parts Discussed in Thread: TPS23754 , Hi,
I am looking for a PoE controller that can power a few 24V Current Loop transmitters.
Most of the devices seem to support only 5V or 3.3V ?
Are there any devices that supports 24V output…
Part Number: TPS23756 Other Parts Discussed in Thread: TPS23758 , PMP40514 , , TPS23730EVM-093 Today I learned that there is a difference between forward and flyback transformer and inductor requirements. Would would have anticipated such a thing?!
I have…
Hi Kazuya,
Thanks for your reply. TPS23756 ( https://www.ti.com/tool/TPS23756EVM ) is a reference design has 12V - 60V input voltage. It is an isolated 25.5W PD + DC/DC converter. TPS23756 has a max 9.3-V UVLO at VC pin, but considering oring diode Vf drooping…
Part Number: TPS23756 Hello,
We have implemented TPS23756 into our Wifi access point product which uses POE or external power from 12V to 48V. Whenever voltages is around 24V or 48V using adaptor, the TPS23756 (or its whole circuit including transformer…
Hi Gareth,
Thanks for reaching out. Please see the suggestions below:
Suggestion 1: You can use TPS23753A's converter components or refer TPS23756. TPS23756 is similar with TPS23754 but has different VC UVLO voltage.
12V 1A: TIDA-00091 or PMP40514…
