  • Power supply for a satellite receiver
    Patent number: 6996389
    Abstract: A power supply for a satellite receiver system includes a dual input supply voltage arrangement. When a higher output voltage is selected, a source of a lower supply input voltage is coupled to an input main current conducting terminal of a series pass transistor. On the other hand, when a lower output voltage is selected, a source of a lower supply input voltage is coupled to the input main current conducting terminal of the series pass transistor. A comparator senses a magnitude of an output voltage produced by the series pass transistor. When, as a result of an over current condition, the output voltage is lower than a reference threshold level, any selection of the higher output voltage is automatically overridden and the source of the lower supply input voltage, instead, is coupled to the input main current conducting terminal of the series pass transistor.
