Got 45 volts out of this thing

[jubal81]

Found some boost converter boards on eBay and took a shot. I can get up to 45 volts off my One Spot and it was perfectly quiet powering a plex drive. The best part is they're only about $2.50 each

This look like the part?

If so, it'll do inversion too and it runs at 400kHz and claims 94% efficiency. Now to find the parts somewhere.

That one looks like it's a buck converter and will only step down the voltage.
