LM5116: Feedback for inductor's specification

ArTzy

Part Number: LM5116

Hi Experts,

Good day!

I have a case where client has some feedback with our reference design from WEBENCH tool with regards to the inductors specifications described from their BOM's list. Their DCR and IDC are different from the datasheet (other manufacturer). See them below.

From this design, L1 is described with values:[ 5.6uH, 4.44mOhm, 21A ] while its datasheet tells values:[ 5.6uH, 12.2mOhm, 15A ].
While in this design, L1 describes with values:[ 10uH, 9.33mOhm, 17A ] while its datasheet shows values:[ 10uH, 18.92mOhm, 12A ].

I am posting it here for feedback since we can't access the feedback feature from the WEBENCH field.

For your information.

Thank you!

Regards,
Archie A.

Hi Archie

The WEBENCH links are broken. Would you please send them again ?
