Part Number: TIDA-010047

Hi

I want to know what is the voltage value of each coil in T1 transformer?

I found the BOM form in the reference design you provided on your company's official website, and found that the model of T1 transformer was 750344183. However, I could not find the transformer information on the official website, could you please tell me where I can find it?
Attach your official website reference design link:www.ti.com.cn/.../TIDA-010047
Thanks a lot,

Best regards,

Paul Han

  • Hi Paul,

    T1 is designed specifically for TIDA-010047 by Wurth. Most of the features are listed in TIDA-010047 design guide, and you may need to contact Wurth if more detail features required. 

    Please also note that the part number of T1 is updated to: 750344527

    Hi Ryan,

    First of all, I'm glad you could answer my question.But I still have a few questions that I need your help with.
     
    1.There is an inductance LCM2. I checked the datasheet and the PCB package. It seems that there is a little mismatch.Or is there any material changed by the BOM you provided?
    2.Yesterday, you did not reply me about a question, which is the voltage of turns per group of T1 transformer. I did not mention it in the reference document, but only gave us some turns ratio.Can you help me to answer it?

    Looking forward to your reply
    THANKS

    Hi Paul, 

    Regarding your questions: 

    1. LCM2 is common mode chock from Wurth, part number is 744823305. I think the PCB might need to be updated. 

    2. I suggest you to ask the detail design files and datasheet of T1 transformer from Wurth. You can tell them that this is for TIDA-010047. We are not allowed to publish the details of this transformer.

    Hi Ryan,

    I haven't contacted you for a long time,I still have a few questions for you to answer.

    The following:

    1.In 010047, the TPS65987DDHRSHR chip needs to burn a configuration file. Can you provide it to me?(I don't know much about configuration software)

    2.This TPS65987DDHRSHR chip will output voltage by default?

    Hi Paul,

    TPS65987 part circuit is designed by our another engineer, I have looped him here for more comments.

    hi,

    1, TPS65987D's configuration file is very easy to generated by the developing tool. you can try it first, if you meet any problem you can post it with new thread.

    2, Its default output voltage is 5V1A.

    Thanks a lot!

    Hi,

    1.I have tried, TPS65987D chip VBUS voltage has been unable to come out, LDO_1V8 and LDO_3V3 voltage is available, I want to ask what is the reason?

    Hi Paul,

    The designer is on a business travel this week and will come back to office next Monday. 

    I will remind him about this question by next Monday.

    Thank you for your patience.
