Sure! In a boost converter like the one based on the LT8410EDC-1#TRMPBF, $R1$ is typically part of the feedback network used to regulate the output voltage.

For the LT8410EDC-1#TRMPBF, the feedback network is set up using a voltage divider formed by $R1$ and $R2$, which creates a scaled-down version of the output voltage. This scaled-down voltage is fed back to the feedback pin (FBP) of the IC to ensure stable output.

Here is a breakdown of its role:

Let's look at the connections:

The feedback equation can be expressed as: $V_{OUT} = V_{REF} \left( 1 + \frac{R1}{R2} \right)$ where $V_{REF}$ is the reference voltage.

Thus, by selecting appropriate values of $R1$ and $R2$, you can set the desired output voltage. In your case, with $R1$ = 604kΩ and $R2$ = 412kΩ, the output voltage can be determined by rearranging the above formula.
