WEBENCH® Tools/TPS40060: The inductance heating in the circuit designed by TPS40060 is very serious (+80°C)

User,

Before I check your design I'd like to know why you chose this part. For 48VIN, 12VOUT at 1A you could use one of many converters. For example you could use LMR36015, a 60V, 1.5A converter with smaller solution size and WEBENCH supported design.

Dear Sam

    Thanks for your support!

    This is an old project. P/N has been selected and can not be replaced.

    Can you check the parameters of the circuit for me? Thanks!

User,

Sorry for the delay. I will forward this to someone on the team who supports this particular device more directly. He will reply to your inquiry.

The DC power loss in the inductor depends on the output current and the inductor resistance.

The AC power loss depends on the type of inductor.  You can multiply the square of the load current

and the inductor resistance to get the DC loss.  You will have to go to the inductor manufacturer to

determine the AC loss and ask them how to determine the temperature rise of the inductor.
