Goofing around with development on getting > 26 vDC out of a 9 vDC supply:

I’m simulating load with the big 1k resistors. Unloaded I get around 29 vDC. It drops to around 27 vDC with one 1k and 25.6 vDC with 2 in parallel for 500 ohm.

This was just proof of concept and I don’t have any LT1054 on hand so I used a MAX1044.

My assumption is that the 500 ohm of loads simulates a 50 mA current draw. This will be for a UniVibe so I’m unsure the exact current draw of the whole circuit and a LT1054 is probably going to be required to provide enough output current.

Am I correct in thinking that the diodes in series regulate the voltage regardless of current draw?

As far as I can tell the voltage stays put but decreases with increased current draw.

The biggest hurdle I see is maximizing delivered voltage without affecting the amount of current delivered. I’d like to 60-70 mA on tap if possible but I’m not sure that’ll be possible.
