Hello, my component level electronics is poor at best so please help me.
I need to take 7v to 18v (ish) Bipolar DC, step it up to 16v DC Unipolar.
I've got my power input sorted with a decent voltage regular and an off the shelf DC to DC unit will get it up to around 18v/20v and I can regulate that with a 16v fixed or adjustable regulator, but because my electronics knowledge is so poor, I've no idea how to then make 16v Unipolar to 16v Bipolar.
Output is around 0.2A
Please Help!
Thanks, John
Huh? Isn't that exactly opposite of what the title of your post says?
I assume you want plus and minus supplies referenced to ground . . . for something like working with op amps?
This is often done with a 555 timer connected as an astable multivibrator to derive a square wave that can invert the polarity.
A search of = 555 voltage converter, yields a lot of info. . add "-frequency" to weed out frequency to voltage converters.
Many types of voltage converter circuits
Many Thanks,
This has put me down the right route!.
Thanks, John
