Re: [TCML] DRSSTC weird waveform behavior

["Bart B. Anderson" <bartb@xxxxxxxxxxxxxxxx>]

Regarding the Excel spreadsheet for the UD2. Note item 9 should be 
UCC27423D (8-SOIC package), not UCC27423DGN (8-MSOP-PowerPad). Minor 
thing but it is nice to get the right part the first time.

BTW Steve, that 100k across C5 really helped my feedback for my DRSSTC! 
I also ended up at 2 ohm on the gate in the end. Thanks for the help! 
Hope to have some 4th of July fun tonight!

Take care,
Bart
