Part Number: PMP20859 Other Parts Discussed in Thread: LM5020 , TPS3808 Hi TI,
Is the reference design of PMP20859 able to output Vout with only Aux 48Vdc input and with disconnected PoE input? The reason asking this is because Vout would be 0V initially…
Part Number: PMP20859 Other Parts Discussed in Thread: LM5020 Hi expert,
May I learn with you how does the circuit work to turn off POE2 to let it as standby mode when both POE1 and POE2 are connected?
Thanks,
Allan
Part Number: PMP20859 Other Parts Discussed in Thread: TPS2372 We have successfully implemented a dual PoE & external 48V input based on the PMP20859 reference circuit, which works fine. External 48V in only, works. PoE swapping over works no glitches…
Part Number: PMP20859 Other Parts Discussed in Thread: TPS2378 , TPS2373 , TPS2372 Hi expert,
Could TPS2378 achieve the Dual-Input Redundant PoE PD like that in PMP20859? Thanks.
Part Number: PMP20859 Other Parts Discussed in Thread: CSD19538Q3A What is the purpose of the MOSFET's in the POE input bridge rectifiers (eg Q1, Q2, Q3, Q4 - CSD19538Q3A) of the PMP20859 ?
Part Number: PMP20859 I require a dual PoE input design, but no external 48V input, so do I just delete the components ringed below. Looks like I won't need the 48V input connector, 48V sense control and 2 off circuits to pull (PoE) PG low if external…
Part Number: PMP20859 Hi team,
I found that we have PMP20885, PMP20940 those two reference designs, could you please s h are the PMP20885, PMP20940 design documents to customer for reference?
Looking forward to your reply.
Part Number: PMP20859 Other Parts Discussed in Thread: TPS2372 Hi,
I would like to ask why R35 is configured to 27.4k ohms? This contradicts the TPS2372 datasheet which recommends 24.9k ohms.
Thank you,
Sith
Part Number: TPS23754 Other Parts Discussed in Thread: PMP20859 Tool/software: Hi Sir,
if i want to switch between DC adapter and PoE , i need hotswap without reboot. how to do it?
the current approach is to give DC priority and will restart once when…
