I received the TMDSHVBLPFCKIT EVM, and followed the instructions to run the first experiments. I was able to connect to the board with the GUI without connecting the 220 AC. I then removed the 12v power supply, disconnected the GUI, and connected the 220v AC. The moment I switched the AC on, the Thermistor (RT1) blew up.
Has any one seen this happening ? Did I receive a defective part from TI ? What other tests can I do to get this going ?
Any help is much appreciated !
