Hello Team,

I have a question about how to use Webench.

How do I change to FPWM mode?

Best regards,

I don't see any way to do this. But I will move this to the Webench forum. Maybe they will know.

Hi Kato,

Thanks for using WEBENCH. In order to enable the FPWM feature on WEBENCH, please check the “User Sync Frequency” option under “Use Advanced Options”, and then hit Re-create Design” (steps shown in fig. 1 below).

Please note, the FPWM feature will provide a better load regulation under light-load condition, however, PFM/PWM mode will give a better efficiency for light-load situation.

Vishwanath

Hello Vishwanath-san,

I checked the "User Sync Frequency" option and did "Re-Create Design", but the efficiency graph looks like FPWM as follows.
Efficiency will not be lowered at light load. Is there something wrong with it?

Kato
