Hi Sir,
My customer used IC VCC connect to D202 positive side, when plug adapter many time has cause TS burn,why?
we have modify VCC connect to D202 negative side, burn issue has never occur.
Thanks
Hi Jericho,
It looks like they are trying to change the bias of the TS pin by connecting VCC and Vref. The TS pin should only be biased by the Vref pin, as seen in the typical application circuit of the datasheet.
