Very good guy to share scope technique and how to troubleshooting skillset. THANKS A MILLION !!!

You can use any digital ammeter with the MAX/MIN function on hand. You don’t need to use an oscilloscope. You can also calculate whether the chip’s protection voltage has been reached from the current on the load side. I used to be a technician in the R&D lithography department of tsm.
