You must open a support ticket and enter all that stuff. There are, however, still those "good old day" companies with nearly unconditional support. Linear Technology, Supertex, for example. And from my desk they have been richly rewarded for that with design-ins and subsequent sales.

Not many people out there who would grab half a pound of ferrite and run it full bore. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

I'd love that but I am afraid the dsPIC ain't gonna be that large in hysteresis. Since I am not a chip designer I can't go in there and fix it :-) But hey, this year I get to do a high voltage chip. Haven't done one in over ten years. Well, only architecture and guidance, not the transistor level stuff (except for some). -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
