Could?? be the Fake Clone Chinese "Tripath" Chip?? Tripath closed it's doors... in say what 2005?

But if they made tripath clone chips like this, it means they almost succeed.. Anyway, Before inductors there is 800khz after inductors 50khz still there without any signal... ••• More options Share Pano Administrator Joined 2004 Paid Member 2018-05-07 2:58 pm #943 2018-05-07 2:58 pm #943 The 800kHz is correct for the Class-D Tripath switching. The 50kHz is likely an ocilation somewhere outside the chip. Maybe an opamp buffer or some other active part that's not the TA2020? ••• More options Share starbender Member Joined 2012 2018-05-07 3:01 pm #944 2018-05-07 3:01 pm #944 Hi Pano, It's sure ta2024 board.. There is no active part other than the chip itself.. Seller sending another board btw.. ••• More options Share Pano Administrator Joined 2004 Paid Member 2018-05-07 3:06 pm #945 2018-05-07 3:06 pm #945 Thanks for the info. I never had a TA2020 oscillate on me, so can't be much help tracking down the problem. Good that you are getting another board. ••• More options Share Prev 1 … Go to page Go 46 47 48 First Prev 48 of 48 Go to page Go Show hidden low quality content Status This old topic is closed.
