LM25122-Q1: Efficiency tool for 2phases design

Part Number: LM25122-Q1

Hi team,

Could you provide me LM25122-Q1 efficiency tool?

My customer would like know the efficiency with below conditions:

VIN = 10~16V

Vout = 24V

Iout = 0~6A

Ambient temperature = 75C

Two phases operation

I tried Webench but I can't generate two phases condition.

Thank you.

Regards,

Allen

  • Allen,

    Thanks for reaching out with your question and using the LM25122. There is not a spread sheet that calculates the efficiency for the LM25122. It would be possible to simulate a single phase design in  WEBENCH with and output current of 3A. This should be able to provide a rough estimate of the total system efficiency.

    Please also take a look at the below reference designs that have similar application specifications.

    Please let me know if you have any questions.

    Thanks,

    Garrett
