Hi,

My customer has two questions for LT4293 PD application.

1. The description section of the LT4293 data sheet states that LT4293 includes undervoltage lockout. But there is no further explanation.

    Could you please provide the operation condtion of…

I am looking into using the LT4293 for use within a design; however, I am confused about two issues.

Looking at Table 6 in the LT4293's datasheet (LT4293 Interoperability), it shows that 802.3 lower class PSE devices will agree upon demotion for higher…

I'm studying the DC2911A datasheet (Evalboard for LT4293).

Table 4 lists the interoperability between PSE and PD. The blue shaded region is labeled as "PD has been demoted or denied power".

How will that demotion work in practice? Will the…

Hello,

My customer wants to design a IEEE802.bt complient PD module with overvoltage protection function for over 100V using the LT4293 + the LT4321.

Could you please provide any information fot the above application ?

Thanks.

Hi,

My customer wants to implement PoE system up to 123W using the LTC4279's UltraPWR mode.

However, ADI's PD devices only support up to 90W(LT4275, LT4276, LT4293...).

Could you please provide reference material for a PD design that supports 123W…

To whom may it concern

Hi, I'm HS.

LTC4279 datasheet specifies ultra power mode regarding 'custom pd'.

I wonder what 'custom pd' specifically mean with respect to LT4279.

It'd be lovely if you enlighten me how to design the custom…
