Part Number: LMR10530

Hi, we are designing a router that requires the following voltages but we want to see if you can help us with a reference design using TI components

We area considering the following components

Any support is welcome

U1          LM27342MY/NOPB                    

U4          LM27341MY/NOPB                    

U16        LMR10530XSD/NOPB               

U3          LMR12020XSD/NOPB               

U5, U17     MAX16907SAUE/V+    

U1

U4

U16

    Hi Sergio,

    Thanks for reaching out to us. Can you tell me what exactly is being driven by the output rails here. I can then check if we have any corresponding reference designs. Also when do you plan to go into production with this design?

    Best regards,

    Varun

    Hi John

    the output rails going a WiFi RF SoC 

    We want to produce in Q1 2022 at least 1,000 units and 5,000 from Q2 to Q4 2022

    Best Regards

    We believe that the problem for which the power rails are not working is because we do not have the correct inductors.

    Hi Sergio,

    You can find a list of reference design for wireless router power here Reference-designs

    1. Do you already have a prototype board where some rails don't work as expected? Could you elaborate more on what is not working?
    2. Do you also have any soft start or sequencing requirement for the SOC?
    3. Could you let me know what features of the DC-DC like efficiency, voltage accuracy, transient response, package, price etc.. are important to you?

    For the 5V to 0.9V, you could maybe consider the TPS6286810CRQY. Even the LMR10530, you mentioned is in stock and would work for this rail.

    My product line only supports <6V VIN Buck converters. If you are open to hearing about other buck converter options for the rails running from the 12V input supply, I can later move this post to our Mid VIN team.

    Best regards,

    Varun
