摘要： A power converter that gives priority to the high power output and only provides power to the low power output when the total potential output power is equal to or less than the rated power of the power converter. A specific power threshold is established, and when the high power output remains below this threshold for a period of time the low power output is allowed to turn on. If the high power output subsequently exceeds this threshold for a period of time, then an electronic circuit powers down the low power output in order to keep the total output power below the rated power of the power converter. Subsequently, the high power output is checked against the threshold to determine if the low power output can be turned on again. If the high power output is below the threshold, then the low power output is turned on.

摘要： A peripheral power hub (PPH) (44) providing power to a plurality of outputs (46). The PPH provides multiple predetermined DC voltages which may be converted by an associated voltage converter circuit (28) to provide the power requirements to an associated mobile device (72). Alternatively, the voltage converter circuits (28) may be internal to the PPH. A programmable Ac/Dc converter (42) may provide a DC voltage to the PPH, which may be configured as an an accessory while powering another mobile device, such as a laptop computer (50). The voltage converter circuits (28) may be buck circuits or boost circuits depending on the application.

摘要： A power converter capable of receiving either an AC input voltage or a DC input voltage and generating a programmable DC output voltage. The converter comprises a first circuit that converts an AC input voltage to a predetermined DC first output voltage, and a second circuit that converts a DC input voltage to a predetermined second DC output voltage. The converter also comprise a third circuit which is adapted to receive the first and second DC voltages from first and second circuits to generate a selectable output DC voltage. In selected embodiments, the first and second DC output voltages provided by the first and second circuits, respectively, are generally the same value and are coupled to a common node that feeds the input terminal of the third circuit. Moreover, the third circuit is adapted to provide a selectable output DC voltage which may be set higher or lower than its DC input voltage. The third circuit may also be adapted to couple a set of removable programming keys that provide for a different associated DC output voltage. The programming key comprises a resistor, which may provide for a variety of functions, such as current-limiting, over-voltage protection, output voltage programming, and wrong-tip circuit protection.
