LM5007: LM5007 inverting mode to generate a negative voltage

Eyke Liegmann

Part Number: LM5007

I found this artikle using an LM5007 as an inverting buck-boost converter. But this is not specified in the TI data sheet, even though the document seems to be by TI itself.

Now I am wondering, does this actually work?

Hi Eyke,

I think in general a buck converter can be converted into an inverting buck boost topology.

There is one article that discuss on how to do this and what you need to do in order to use a buck as inverting buck boost

Thanks
