LM5576: SD pin of LM5576 in inverting configuration

Hello

The SD pin will need level shifting if you need to enable and disable the converter in an IBB application.

I have attached an application note that should be helpful, it describes the connections for IBB and level shifting.

You may also want to look at SLVA540.

Also, the Webench design tool is set up for IBB for the LM5576.

Thanks
