Hi Sayzer,

To me, HPWM looks simple. But, as you say, why not another way?

Never used a Digital pot before. What "resolution" (roughtly voltage step) will I get?

Any suggestion of values I should use in this case and what the schema would then look like?

If I stick to the HPWM, what value should I use for the resistor to be put parallel to the cap?

Thank you in advance
