Hi all

I need to convert +12 to -50V at say an Output current of 100mA.

Whats the easiest and cheapest.

Thanks for any suggestions.

an NE555,a MOSFET, an inductor and a diode plus some other stuff to
limit short circuit current and limit the output voltage under no-load
conditions.

So I entered Vmax_in 500, Vmin_in 15, Vout 12, Iout 200A, Tamb 40

'Your solution is not yet WEBENCH (tm) enabled :-(
Then I clicked 'why'
It seems it cycles through all their chips...
But also with the OPs spaces.
