TPS92560 SRC pin

RVG
Intellectual 720 points

Hi,

Would like to enquire of this SRC pin is recommended to connect direct to ground? Based on ref design, EVM design and datasheet, it stated that the pin should be connected to the Mosfet source pin.

However, the design is having some radiated EMI issue and FET vendor is proposing to ground the pin as the connection to the Source cause difference in potential and hence the issue.

Would need advise.

Thanks.

RVG
