The charge pump is a voltage multiplier too. That lashup just uses the pins supplied with the 1363 power supply, which delivers DC. To make a doubler/tripler/multiplier/charge pump work, you need AC drive. Michael derived this from the DC with the 4093 oscillator and some switching transistors. However, there is an AC signal available on the 1393 module (though not on its connector), as jt detailed here: http://ppl.ug/IEd55TCltCo/ Michael's circuit predates that post, so it doesn't take advantage of it. Either approach will work. > What are the advantages of pumping the voltage up using the charge pump as > apposed to the regular doubler or tripler? > > I think I should read up a bit on them lol. You'll find out that they're just different terms for the same sort of thing. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
