Hello,
I need to output -5V voltage using LM22678-5. But when I using the WEBENCH to calculate the component value, why can't I find LM22678-5 among the given schemes.

Hi there,
The LM2267x family is not currently setup for inverting applications in WEBENCH. Sorry for the inconvenience.
If you are wanting to use this part in this topology I would suggest taking a look at the LM22670 Inverting EVM and also an appnote for converting a similar series of parts to the Inverting topology.
