I was looking for a solution for generating dual power rails from a 3.7V LiPo battery. I found this DP1912PA board that seems to do a good job generating ±5V. I drew a schematic so I can integrate it into a design.

Once again the design was mostly taken from the datasheet. Interestingly the datasheet shows the three inductors as part of a dual-secondary transformer. This seems to be a mistake.
