Hi! I would like to adapt the design found here <http://www.desmith.net/NMdS/Electronics/NixiePSU.html> for a variable 300V max output, instead of around 180–220V:
<https://lh3.googleusercontent.com/-s-0Y3HUtvnQ/WWZxbEdcAtI/AAAAAAAABl8/kj1ECWl4iR0tEYFTyzObW48sHwiO4erSACLcBGAs/s1600/Screen%2BShot%2B2017-07-12%2Bat%2B2.59.12%2BPM.png> I understand that the output voltage is adjusted by the resistors R1 and R2, per the MAX1771 datasheet <https://datasheets.maximintegrated.com/en/ds/MAX1771.pdf>: <https://lh3.googleusercontent.com/-dpjgDtRGWhg/WWZxvx4w4II/AAAAAAAABmA/GhOM6eWGUVg-WVsYlIytvXjMQjOpjOolQCLcBGAs/s1600/Screen%2BShot%2B2017-07-12%2Bat%2B2.59.00%2BPM.png> and that in this case a potentiometer is used to vary the voltage of R1. However, I'm not sure how the above equations are used to arrive at the voltage bounds specified in the schematic. Could someone explain? Using those equations, what value of R2 should I substitute in for the one used in the schematic to arrive at my desired maximum voltage of 300V?
