Hi,

The following is an example of 3-pin AC inlet with no earth GND application. You can follow the same for 2-pin AC inlet(no earth GND) application

Best Regards

Hi Naresh,

In my customer's application, they connect Y-cap to AC/DC secondary side GND(also the GND for PSU Vout), so could I connect AEF IC's GND to PSU Vout GND?

Regards,

Charles

Yes Charles, you can connect them together - If you also have common chassis, IC ground and PSU Vout GND can be connected to the common chassis.

Thanks and Regards,

Naresh
