Charge pump help?

[therecordingart]

I'm looking to get 24v from either my One Spot or from a 12vdc power supply I have laying around. Anyone know how to do this? Any charge pump masters out there?

I'm no expert...but voltage is only half the story...the secret to speci'ing a good charge pump circuit...is in large part knowing what your current draw is gonna be.

Not sure....it's for this guy.

Take the 12v DC supply and get a LT1054.  The datasheet for said chip has a simple voltage doubler 'schematic' for the chip, and it accepts up to 15v at it's 'input.'  And it does it quietly.

The chip can handle a current load of 100ma.  That circuit and an LED light show will be powered by 100mA just fine.

wondering as to where is the volume pot on that guy?

it's right there between the diodes at Q4 and the voicing pot
