bitfury power strings

[ssi]

Has anyone done a successful design with power strings using bitfury chips?  I want to turn a new module PCB, and I'd LOVE to get rid of the expensive regulators. I've seen some of bitfury's notes about how to do power strings, but I don't fully grok it.  I'd love to chat with anyone who's got some experience or knowledge about it

IMHO without external components it won't be working. I have an idea tested on 3 3,3V uC's (worked fine from 10V PSU) but I don't have bitfury chips to test with them.
