Boost converter using TL5001
this chip aims for 1V on the FB pin and wants about 100K of resistance or lower.

Replaceing  R4 with 91K and R5 with a 500K potentiomer
would get the voltage divider range needed but the resistance would be too high.

so reduce those and R3 by a factor of 5:

replace R3 with 2.0M  R4 with 18K and R5 with a 100K potentiometer.
