• RE: ADP2164 and ADP2164-1.8


    I see you said FMCOMM2 and not FMCDAQ2. if you used the same ferrite bead then instead of the inductor you are good.

     Requesting for clarification on SYNC pin of ADP5054 and ADP2164, on high priority.zip

    Hi All,

    I have a query wrt the SYNC pins of ADP5054 and ADP2164.

    In the Power Section we are deriving 4 voltage nets required for AD9364 - 3.3V, 1.8V, 1.3V_A Supply…

  • About ADP2164


    I have some questions about ADP2164.
    In my system, it requres to use different power rails for VPIN and PVIN like the attached file.
    These two inputvoltage are not applied to ADP2164 at the same time, there are some delay times between 5V_1 and 5V_2…

  • About Exposed Pad of ADP2164


    My customer want to know that the Exposed Pad and PGND/GND of ADP2164 are connected internally or not.
    According data sheet of ADP2164, there was no information of that.  Could you please let me know if you have this answer.

    Best regards,


  • About EN pin on ADP2164

    Hi there.

    I have something to make sure about EN pin of ADP2164.


    I just want to know the enable/disable area.

    I drew a diagram, so please check the attached file.


  • RE: ADP2164 Forced continous switching

    Hi Dave,

    The ADP2164 operates only in continuous conduction mode (CCM) even at light loads. With this, you can proceed with calculating the RT to set the switching frequency to 650KHz. You can double check your design by using the ADP21xx design tool…

  • RE: About PGOOD of ADP2164


    The PGOOD pin should be pulled-up to a voltage lower than 6.5V.

    A pull-up resistor of 10kohms is typical.

    Please let us know other concerns.



  • AD9364 Power supply query


    Currently we are designing a custom board based on AD9364 chipset. I had referred the Evaluation board for the power supply section. The EV board contains the 3.3V to 1.8V conversion  using ADP2164 chipset which is 4A capable device.

    Also there are…

  • RE: driving the AD9364/65 with switching supplies?

    Hi Sripad,

    If you look closer at that page on the schematic, you will see that the VDD_INTERFACE node is driven by the ADP2164 switcher. The customer is very concerned, so we are trying to make sure we all agree on this.



  • About tracking function.

    Hi there,

    I checked the tracking function on ADP2164 evaluation baord.

    But the resut was a little bit diffrent from what I expected.

    Please look at the attached file and give your opinion about this resutl.

    ( I guess it was affetected by resistance…
