The customer would like to use to PD input(TPS23754) with current sharing ic(ucc29002). Dose TI have reference design?
For 50W(25+25) application. Dose…
Part Number: TPS2378 Other Parts Discussed in Thread: PMP20859 , TPS2372 Dear team
The customer's PD application will have two POE input(back side and bottom side), the application condition : The POE input will source by different PSE device. But …
Part Number: TPS23751 Other Parts Discussed in Thread: PMP20859 , TPS23731 Hi team,
I know we have reference designs with two PD solutions for dual inputs redundant application but wondering if somehow it's feasible to use just one PD or what are the concerns…
Hey Kai,
One example is PMP21115. I can send it over email and you can share with the customer. It is a dual PD, dual DCDC design that has power sharing and power limiting. There is also a 12V adapter. the DCDC output is 12V. The adapter and DCDCs combine…
Hello,
This is expected behavior. Having the output voltage never drop is called "smooth transition" or "hitless failover" in PoE market.
