摘要

Many systems require a±12V power supply. Typical exam-ples include analog circuits or RS-232 driver power supplies. The ±12V typically needs to be generated from a SV system bus. The solutions normally used involve a multiple secondary transformer or multiple switching regulators. These solutions can be complicated,
