Abstract
A circuit portion comprises a DCDC converter arranged to provide current from an output of the converter to one of a plurality of loads at a time. The plurality of loads includes a low priority load and a primary load. In response to the controller detecting, while the DCDC converter is providing current to the low priority load, that the voltage across the primary load is below a first threshold, channel logic circuitry is configured to stop providing current from the output of the converter to the low priority load and to provide current from the output of the converter to the primary load. A voltage regulator provides current to the low priority load when the voltage across the low priority load is below a second threshold.
Claims13
A circuit portion comprising:
- a DCDC converter arranged to provide current from an output of the converter to one of a plurality of loads at a time, wherein the plurality of loads comprises at least a low priority load and a primary load;
- a controller configured to detect when a voltage across the primary load from the DCDC converter is below a first threshold for the primary load;
- channel logic circuitry configured, in response to the controller detecting, while the DCDC converter is providing current to the low priority load, that the voltage across the primary load is below the first threshold for the primary load, to stop providing current from the output of the converter to the low priority load and to provide current from the output of the converter to the primary load;
- and
- a voltage regulator configured to provide current to the low priority load when the voltage across the low priority load is below a second threshold for the low priority load.
