TPS23754: Power inductor and reference design of TPS23754

user6289930
Prodigy 40 points
Part Number: TPS23754
Other Parts Discussed in Thread: PMP6812,

Hi team,

Could you help me to check these questions?

1) What reference design is the attachment from?

2) Are you have any concern if the power inductor changed to 1uH 3.0A and the info of inductor shown below you.

Thanks,

    Hello,

    1.) This loosely looks based off of the PMP6812 since it is a 12V diode rectified flyback with the TPS23754. 

    2.) The inductance current rating must withstand the maximum current value on that node. You can calculate the current in section 2.7.5 in the following paper: http://www.ti.com/lit/an/slva305c/slva305c.pdf

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
