Building 24 VDC using three 9 v dc battery Answered

Hi ,
Any circuit that I can use three 9 vdc battery to get 24 VDc output less than 1.00 amp . The power would be used for demos powering sensor that can accept 12~24 VDC.

A switching power regulator might help, just looking quickly through a search tool on ti's website, it looks like theirs several options. The TL5001 looks nice because its in a package that can be used on a protoboard. In fact looking at this, I might want to try my hand at making a 12V-5V for a usb charger for my car.

2 '3S' LiPos may be a good option? And rechargeable.

some 9v batts are comprised of individual cylindrical cells resembling aaaa cells. remove 2 cells , and have a 6 v batt. 9+9+6=24.

coppertopp is one mfg with cells that can b separated.

3 x9 is 27. you might be able to get away with a little overvolt. If not, just put a volt regulator in there.

I am trying make simple power supply which uses 9 VDC battery so we can demonstrate sensor on desktop without having to have AC outlet.

9V batteries are not know for thei high amp ratings, so you have to keep an eye on the power consumption and battery levels for proper operation.

If the sensors are happy with 12V I would prefer a small 12V lead acid battery - the closed kind with gel as a electrolyte.

For 24V use a buck converter if necessary.

Could you be more specific or at least tell us what you are planning to do?

I miss the question here.
