Inverting DC/DC controller converts a positive input to a negative output with a single inductor
David Burgoon
Abstract
The use of the LTC3863 to produce a negative voltage from a positive voltage source is described. The LTC3863 is elegant in its simplicity, has superior efficiency at light loads and reduces parts count compared to alternative solutions.

LTC3863
There are several ways to produce a negative voltage from a positive voltage source, including using a transformer or two inductors and/or multiple switches. However, none are as easy as using the LTC3863, which is elegant in its simplicity, has superior efficiency at light loads and reduces parts count compared to alternative solutions. ...
