| Zusammenfassung: | A power supply has a plurality of switching regulators providing a like plurality of regulated output voltages. The oscillators of the switching regulators are synchronized with one another by a synchronization signal. A synchronization signal detector is provided on one or more of the switching regulators to shift the switching frequency of the oscillator to a lower frequency upon detection of a synchronization signal. |
