Hi Mike,
Sorry for the late reply, and thank you for all the great information and the great links...
I'm sure I've had several past projects with badly mounted piezos, and
thanks to this thread I've finally taken the time to look at boost converters. I actually do a lot of my prototyping in smd and I've scrapped the flyback idea for now. (Common mode chokes are quite expensive and have lead times of >2months with farnell.at)
However, I've skimmed the Microchip technical briefs (TB053, AN258, ccp tips and tricks) on the regular boost converters in discontinuous mode, and I will be adding some chip inductors to my next order. Once I get my parts, I will test a small high voltage stepup (Ip = 10mA) and transistor method.
I'm actually not working on an embedded project at the time...
Just trying to learn a bit for future endeavors. The business card link was just an example of a battery driven, tiny gadget (the type of device I like to work on). Also, I was interested in sensing of Voltage spikes, and ways to protect the io pins incase of shock/trauma.
best regards,
Michael
