45. Switching regulator provides ±15 V output from an 8 V to 40 V input without a transformer
    Circuits Linear Technology LT1074
    Many systems derive 15 V supplies for analog circuitry from an input voltage that may be above or below the 15 V output. The split supply requirement is usually fulfilled by a switcher with a multiple-secondary transformer or by multiple switchers. ...
