I'm creating a vary small device that need an high voltage around 50v. But because the device is really small like a pistol bullet, I can only use very small batteries like watch battery or button cell. But I cant use Transformer, also because of the size limitation.

Is there any other way to do that (may be electronically). But the solution need to be small as much as possible and the light weight as much as possible.

  • \$\begingroup\$ A transformer needn't be much bigger than an inductor so in order to answer this question (with this bizarre constraint), you should specify a space envelope and not state "small as much as possible". \$\endgroup\$ – Andy aka Jul 20 '15 at 9:23

One way would be with a boost converter, but the size depends on which Boost Converter IC you use, so you may want to search on mouser, digikey, farnell etc.
