I have never used a potentiometer in my MAX1771-based supplies. The
reason is, they make it more difficult to do a better PCB layout, and
anyway the regulated output voltage from the supply using fixed 1 %
resistors is accurate enough for the purpose of powering a Nixie
display. I could always
Hello.
In my high current MAX1771 PSU design I made several years ago, the
best results I got when I used a toroidal inductor with a current
rating of 10.3 A (Bourns 2200LL-470-RC), and a RSENSE peak current
setting of 5.33 A. I tried other inductors, including a physically
smaller 2100LL series
