Charge Pumps - Switched-Capacitor Voltage Converter

  The Max is rated at 10.5 Volts, so most the time power supplies spike when daisy chained. If you add a 1N4148 then 100 OHM resistor then a 9V Zener Diode to ground, it will protect the charge pump circuit and keep your voltage consistent. But the Tc is a more sturdy chip.

  Thanks for the video, and hope everything goes well with your family.

  that is worth experimenting ... I will give it a try to see if it will pop.

  I&apos;ve made some using ICL7660S - so far no problems, but I don&apos;t daisy chain my pedals. Maybe I should try to see how it behaves. <br>

  +DIY Guitar Pedals How I can take +/-18V of +9VDC? Can I use LT1054 to doubler to get +18V and then inverter +9V to -9V and boost -9V to -18V?

  me too. &nbsp;I&apos;ve been burnt (literraly) by the max 1 too many times..hope you get your maxs going, I think you might have a good chance with those regulators! &nbsp;All the best.

  Yeah that was my other thought. &nbsp;Prehaps a spike in voltage, in for a millisecond, can kill them. Plugging a power plug into another pedal could cause a spike. &nbsp;Regardless, im not touching them anymore :) I&apos;ll stick to the LT or TC, they are just so much more reliable. &nbsp;Thanks for the post, the confirmation is welcome.
