1. It seems to be an infant mortality problem with the switcher control chip, a National Semiconductor LM3485
2. There is already a TVS (transient voltage suppressor) on the circuit that feeds the LM3485 -- so it may NOT be a voltage spike related failure (28V TVS on LM3485 power line, LM3485 part is rated to 36V operational,) but we are not ruling out the possibility at this time.

We are working with National Semiconductor to determine the cause of the failures. It seems that making a couple minor changes to the circuit make everything work fine -- but we haven't determined the cause of the failures yet.

Thanks for the information Patrick. I just have a hard time swallowing information from someone other than those who actually work at Castle. It's one thing for someone to speculate upon the failures, but it's entirely another for one to dissemenate information about failures from Castle as a 2nd hand source. If indeed someone at Castle is speaking with RURC regarding these failures, you guys should keep an eye on how your PR looks with someone like him speaking like he works for you. However, if he's just some crackpot trying to solve the world's problems, then you guys really should make it known that he is not affiliated with your company because he's really not giving anyone warm fuzzies about the whole situation.
