Hi,

I'm fairly new with boost converter and I don't understand why, I have such a difference between Vout Actual and Vout when I look in Webench report. My parameters are the followings:

Vin = 22-28VDC

Vout = 110VDC

Iout = 3.2A

Thanks in advance for your help!

Hi Antoine,

Thank you for considering TI products. The feedback setting is correct and it sets to about 110V. I need to check with our webench group for an explanation of Vout Actual.

Thanks,
