I was testing 5010, when 5010 started to work, but after more than 5010 can only use a few times and 10V output voltage waveform is a sawtooth waveform rendering, after 5010 for a new ready to use.
When in use after 5010, the use of electric soldering iron around 5010 devices will damage some of 5010, appears to ask me these two issues and what relationship? Is the layout or schematics have a problem?
