LM25141-Q1: Adjustable output controlled by DAC output

Ryo Akashi

Part Number: LM25141-Q1

Hello experts,

I have question for LM21541-Q1.

This device has two mode, fixed output mode(3.3V, 5V) and adjustable output mode.

In adjustable output mode, I would like to make some output voltage with VDAC output like as this picture.(http://www.ti.com/lit/an/slva861/slva861.pdf)

Is it possible?

Thanks and best regards,

Hi Ryo,

Yes you can do it.

The Rtop and Rset in the apps note is now your top and bottom feedback resistors.
