LM5170: lm5170 power loss calc

Part Number: LM5170


where i can find power loss calculator that give the optimaze componnents and high efficiency?

can i simulate the LM5170 in the webbench?

Thank you.

  • Hi Ilan,

    Thank you for your interests in the LM5170.  Sorry our calculator can help you design but it does not yet include the efficiency calculation.

    Since it is just a buck or a boost, depending which way you operate it, you can follow regular buck or boost losses calculation to estimate the efficiency, and do some adjustments for optimization.

    Currently we have not completed the weebench model for the LM5170.  However, you can simulate it in Pscpice or TINA.  Please find the models at the following link:
