**Hi to all:
On March 13 this year - poster " Hammy" raised a few valid questions about
Tech Bulletin " TB 008 " on the Microchip web site ( and quoted widely
elsewhere) on the subject of "Transformerless Power Supplies".
http://ww1.microchip.com/downloads/en/AppNotes/91008b.pdf
This prompted Mr Rod Elliot of ESP to contact Microchip with a view to
having them retract and withdraw TB008 from publication. As feared but
expected, this was not successful.
The ESP site now has an outline of what happened when he complained and
includes the email reply received from Microchip's Tech Support Group.

A second, even stronger worded email from Mr Elliot went unanswered.
Microchip's anonymous tech support guy was clearly WAAAY out of his depth on
the topic of AC mains and appliance electrocution hazards - as was that
fool Stan D'Souza who wrote the infamous tech bulletin.
D'Souza is now a "Technical Fellow " at Microchip - so I guess the dude
walks on water and his word is Gospel round the place.
IME - people like him will * NEVER * admit to even the most grievous of
errors nor allow any error of theirs to be publicly corrected.
