In that case measure the current drawn on the -12V rail, make sure you try it under all possible circumstances. Pretty silly spending a lot of time, money and effort generating an amp or two at -12V, only to find you require 10mA or so.

Yeah, I ran some test and observe that I need around 50-100mA in -12V.

That is also not always, but I do not know all and every conditions.
I will try to find more details about this.

If you have any comments about it I will be more than happy to listen.
Thanks
