NE555 analogguru charge pump / supply for IC

Postby Mbas974 » 16 Mar 2012, 23:41

First, thanks to analogguru for this schematic: ... iplier.gif

I did it and it works well until it is open (no connections/supply to main circuit)
As I use it to powering a IC (TL072) for dual supply the charge pump vanish the effect....

So I'm wondering it is designed for Transistor use or there is any special trick I can take for let it working with ant Op-Amp. ??
