Part Number: TPS23750EVM-107 Other Parts Discussed in Thread: TPS23750 Hi,
I recently purchased a development board, but when I found out that it did not work properly, the specific performance is that the OUTPUT port has 5V voltage discontinuity. …
Part Number: TPS23750EVM-107 Other Parts Discussed in Thread: TPS23750 , , TPS23756 Dear expert,
I have designed a PoE buck converter with TPS23750.
In TPS23750EVM-107, there are no specific input voltage.
I would like to double check it with…
Part Number: TPS23750EVM-107 Hi~ TI expert
I measured output voltage ripple of TPS23750EVM-107.
And there was too much ripple at no load condition.
and no change when adding a dummy resistor (120ohm).
It can be improve? or is it normal??
Hi Steven,
If VDD-VSS is 48V, theoretically CLASS should stop and you should not see 10-V between CLASS-VSS. You can check it on your board.
For the regulator issue, sorry that I did not find wrong circuit design from your schematic. Do you think…
Part Number: TPS23770 Other Parts Discussed in Thread: TPS23750 Dear Sirs,
How to modify the TPS23750EVM-107 for 12V output?
My customer wants to use TPS23770 and use TPS23750 EVM with TPS23770 IC for testing.
Please help.
Thanks.
Hello,
Thank you for your question. For 3.3V/1.4A non-isolated PD+DC/DC solution, I recommend TPS23750EVM-107.
Please let me know if this design is not sufficient or if you have any additional questions.
Best Regards,
Brett Colteaux
Hi Tateo,
Yes the Rz will affect the crossover. It will also affect the gain. I think the best approach is to design similar to our EVM or TI Designs which use common PoE output voltages and are known working DCDC designs.
EVM can do 5V or 3.3V…
Hello Apullin,
Since solution height is your main concern, a buck topology, as you noticed, is a good choice. I have 3 suggestions:
1. PMP10812: Low cost 5V/1A Non-Sync Buck using TPS2378 (PD only) + LM5010
2. TPS23750EVM-107: 5V/2A Upside down buck…

Hi,
As per slvs590b.pdf document, the TPS23750 is designed to operate from 24V adapters when we use Auxiliary Power ORing option-2.
Can you please confirm, will the circuit below (reference:TPS23750EVM-107) work if I connect…
