• ADuM5201 DC/DC input filter


    Below is power flow of my ADuM5201 design.

    To reduce EMI from DC/DC inside ADuM5201, I made an attempt to add T filter just ahead of ADuM5201.

    The result was as follows:

      - Much heat was generated from LDO. It was hot.

      - Data transfer via…

  • Increasing Available Power of iCoupler devices



    In the chapter (page 23) of ADuM5200 datasheet (and in ADuM6200 datasheet too), AD explains how to increase the output power by using 2 devices (one as master and the other one as slave). This is a good thing but it is not as clear (for me…

    Yes, I meant to type "ADuM5201".

    Thank you very much for your assistance!

  • RE: can bus isolation

    Hi Yang,

    The ADuM5201 is a dual-channel digital isolator with isoPower , an integrated, isolated dc-to-dc converter.

    The ADuM5201 is can be used to isolate the CAN TxD and RxD signals.
    This part can also be used to provide an isolated power source to…

  • RE: Are there known ADuM5211 start up issues?


    1. The ADuM5201 has a different DC to DC startup architecture than the ADuM5211, so an issue with one may not be with the other.

    2. Your schematic for the ADuM5201 shows the VSEL pin tied to GNDISO, which per datasheet Table 11 would make…

  • RE: ADuM5201 self-regulation mode configuration

    Lux: For ADuM5201 in self-regulation mode:

    1) Tie pin RCin direct to GND.

    2) Connect the RCsel pin direct to VDD1.

  • ADuM5201 start up problem


    I am using a Adum 5201 for a Signal isolation. I have problems with the start up of the V_Iso output voltage. Sometimes the circuit is wirking fine, but, if i switch of the +5V supply and turn it on again within 4 seconds, the generation of the…

  • Is there FIT data available for the ADUM5201.

    I would like to know whether there is FIT data available for the ADUM5201. I see in the datasheet there is information on the lifetime related to the insulation requirement but nothing about FIT data. I appreciate there is a lot of uncertainty in these…

  • Regarding ADuM5201 DC/DC switching frequency


    ADI iSopower products such as ADuM5201 have 180MHz switching frequency for DC-DC converter.

    I wonder why iSopower has 180MHz switching frequency.
