Hello !
I would like to make a dc dc converter ,(without to use coil or choke or something like that) in order to get the necessary voltage (180v )to run a "magic eye" tube, on a vu meter circuit. (and some nixie tubes on other circuit )
this circuit runs fine with back to back transformers and has a range of 150 to 250vdc, but i would like to know how i could replace those back to back transformers with a smps 12v/1(or 2) A and a dc dc circuit.
I need about 100ma !
thank you !
