Title: A "Can you do this" question
Post by: insomniac2295 on March 18, 2013, 05:55:56 PM

So, I'm wondering if one could put a Road Rage in a 1590LB box with a DC in and a DC out to act as an external voltage doubler (18v). The idea is one could use it with a regular 9v power supply (like a Visual Sound 1Spot) and power their 18v pedals with it, without having to get a different power supply. Do able? I'm thinking yes, I just want to be sure.

Be careful...per the docs:
Limitations
While the Road Rage offers the convenience of extra voltage with relatively few parts the downside is
its current supply power and voltage tolerance. The TC1044SCPA, MAX1044CPA and ICL7660SCPA
can comfortably supply around 20mA

Alternatives
You can use an LT1054 in place of the charge pumps listed above for approximately 2 – 3x the output
current

So if your plan is to daisy chain some 18v pedals off this you would be quite limited I believe
