POWER: MAX1044 Charge Pumps and Inverter


MAX1044 charge pumps and 9v inverter



Note:  Normal power ripple filtering can be added to these.  Probably better to add filtering after the IC rather than before (or both ends if you are really keen).

Would the 25v work with a 7660s instead of the max1044?

Yes, but they have a lower clock rate and can cause noise.

Hello! Would it be possible to add a sag/starve pot for the -9v version to simulate bad batteries? Thanks!

Sure - that will work with these. I'd add it on the negative side.
