Hi,

I plan to use the LMZ31704 in my design. I need two different output voltages from this device. Can I change R SET during operation to adjust the output voltage?

Thanks

Hi Jens,

This post belongs to the power modules forum, I will move it for you and one of my colleagues will pick it up there.

Hi Jens,
It is not recommended to adjust the voltage during operation as the voltage will try to slew very quickly. It is recommended to shut down, change the Rset and then power up. For mor details you can contact me directly at jarrigo@ti.com.
Thanks, Jason
