• POE with LTC4267-1

    Hi all

    I have a problem with LTC4267-1. I try to use it for an application but when I connect it to the switch the output voltage instead of being 12V as foreseen by the diagram oscillates between 12V and 0V

    I attach the schematics


    Thanks for help…

  • LTC4267-1 PoE Current limitation


    Current Sense Resistor Consideration:

    Please provide any info telling relation between Rsense and ITH/RUN voltage. i.e. ITH/RUN voltage the nominal voltage
    range is 0.7V to 1.9V and RSENSE

    I want to use it in Class 0 (13W , 5V@2.6)

    I am following…

  • LTC4267 Generating 5.5V

    Hello guys!

    I'm doing a project using PoE technology through LTC4267. I did my PCB based on the DevKit 1145B, to generate 5.5V to a class 3 device (up to 13W). I have tested the circuit (attached in this message), and it works, the circuit is generating…

    I have a question of LTC4267-3.
    Could I use output what is 24V and 13W by LTC4267-3 without optcoupler(same as Figure11).

    Best regards

  • About problem of LTC4267-3

    Could you tell me about connection of PWRPD of LTC4267-3.
    Customer has made board nearly to non opto design of DC1249A.

    DC1249 and customer board is difference that Customer has used pull up 10kΩ resistance between PWRPG and PVcc and D8 is 7.5V zener diode…

    Hi All,

    I'm working on a Class 2 POE design simulation in LTSpice.

    For temperature sweep, the simulation is taking so long time and it's almost endless.
    What could be the reason for that?? or Is there any other method to do thermal simulation??

  • RE: ltc4267 PoE - Current limit

    Thanks for the info.

    Actually I want to build a LTC4267 PD that only supplies 5V @ 200mA.
    But there is no formula given in the datasheet  to calculate the sense resistor value.
    Do you know any other method to calculate the Rsense??

    Hi ADI Team,

    We are designing the POE schematic according to the LTC4267 datasheet guidelines for 5V output.Please review and  let us know the feedback.

    Note:We followed as per the reference design https://www.analog.com/media/en/reference-design-documentation…

    Hello everyone,

    I am in search of LTC4267 PSpice model  for my POE switch.

    Where can i get it?

  • LTM4650AIY-1#PBF vs LTM4650AIY-1#3NSPBF

    Could anyone explain what 3NS means on part numbers such as LTM4650AIY-1#PBF vs LTM4650AIY-1#3NSPBF ?

    I cannot find any information.

    thank you
