WEBENCH® Tools/LM73606-Q1: Webench balanced optimization suggesting unreasonable component values, and does not report efficiency figures

Hi,

I will move it to Webench team.

Hi Bryan,

Thanks for reporting this. We're looking into it and we'll keep you posted.

Hi Bryan,

Could you please share the input conditions (VinMin, VinMax, Vout, Iout and Ta) Or share this design with us?

We're unable to reproduce your issue without it.

Hi Bryan,

This issue has been resolved and we are now getting realistic Cout values for your input condition. I went ahead and created design for input condition shared. Please find the attached report for the same below. These change should be available on ti.com by the end of 3rd week of December. We will keep you posted on this.

For Efficiency, light load performance of the device is not modeled on Webench and hence efficiency and power dissipation charts are disabled and operating values are not displayed for PFM mode of operation. Hope this helps.

Best Regards,

Bhushan
