Part Number: TIDA-010081

Respected Sir/Ma'am,

     I want to evaluate TIDA-010081 (1 KW SMPS Reference Design) by myself. In this design there are three transformer as T1,T2,T3. T1 is used in LLC converter as magnetization inductor. 

I'm not getting any details of this T1(Part No- 029H1-001). My earnest request to you ,please provide me any details about T1, so that I can overcome my problem.

I'm eagerly waiting for your reply.

Thanks & Regards.

    Respected Sir,

    Thank you so much for your concern & Reply.

    Here I'm giving my required transformer properties. Please provide me proper type of transformer which I should use for my design.

    Required Transformer Properties:

    1. Turns Ratio(n)=3.6

    2.Primary terminal Voltage=450 VAC

    3.Primary magnetizing inductance=50uH

    4. Primary winding's rated current(Iwp)=18.51A

    5.Secondary terminal voltage= 54 VAC

    6. Secondary winding's rated current(Isw)=34.54 A(center-tapped)

    7.Minimum Switching frequency=44.2KHz

    8.Maximum switching frequency=118 KHz

    9. Insulation between primary & secondary sides= Most suitable according to you.

    Please help me to get rid from this problem. I'm eagerly waiting for your reply.

    Respected Sir,

                           I want to evaluate this "TIDA-010081" with output voltage  as 54 Volt & output current as 42 Amps. For this, which components' value should be modified, please let know. 

    I'm eagerly waiting for your reply.

    Thanks & Regards.

    Hello, you need to contact a magnetics vendor to help you make a transformer based on your parameters above. This will need to be a custom design.

    Thanks,
