Other Parts Discussed in Thread: TPS54295

tps54295是双通道的电压转换，如果要求一通道输出正，一通道输出负电压，这对于芯片的地连接有什么需要注意的，这种正负输出可以实现吗？

If yes, how to connect GND of each channel?

Hi John,

The question in Englishi is just the title of this post:

I think that is not possible as the grounds are common. I would recommend this approach:
