• ADP5052 Rlim pin

    Hi all,

    I am trying to simulate ADP5052 channel 1 and 2 in LTspice there is more one pin on the simulation symbol called Rlim. But there is no pin like that in real IC. What is this Rlim pin on the simulation circuit IC of ADP5052. 

  • ADP5052

    Hello Everyone, 

    I would like to know what is the recommended buck regulator channel sequence  for ADP5052.

  • ADP5052

    Why would I be getting 0.8V output on channel 3 of the ADP5052. I have configured it to match the example given in the datasheet. (Channel 3 is located at the bottom right hand corner. U4 and U5 are seperate chips)

    Also, why is the example in the datasheet…

  • ADP5052 LDO



    I have a question ADP5052 LDO.


    When LDO is not used in ADP 5052,
    Is PVIN 5 OK even with OPEN?
    (EN pin is connected to 0 V)


    Best Regards


  • ADP5052 Layout


    I have a question ADP5052 Layout.

    It is written that inductors and SW terminals are connected to the data sheet with the shortest thick pattern

    In the actual pattern diagram, connections with 3ch and 4ch inductors are narrowing.

  • RE: ADP5052 output

    This captured take from Zybo Digilent reference design. R=0 ohm is function just for be wire to the output voltage so that it's easy for cut the wire if there is problem in output voltage.

  • ADP5052 power derating question

    Dear Engineering Zone!

    I have a question regarding power derating of the ADP5052.

    In the datasheet there is no information about this matter. Also I tried to explore the behavior of the ADP5052 through the ADP505x_BuckDesigner tool. If I begin to increase…

  • ADP5052 GND Layout


    I have a question ADP5052 layout.

    In ADP5052 DS is,

    Exposed Pad connect to 30pin PGND.

    In ADP5052 Simulation tool Excel file is ,

    No connect Exposed PAD to 30pin PGND.

    Which is better for ADP5052 layout?

    (I think both are no problem.)

  • ADP5052 Thermal Shutdown

    Hi Sir

    The ADP5052 be used in FPGA, design in DSO products,

    We to add the hot wind into adp5052,then the adp5052 will shutdown as data sheet mentioned


    If the ADP5052 junction temperature exceeds 150°C, the thermal shutdown circuit…
