摘要： A method for a power adapter to selectively provide a first and a second output voltage may comprise coupling a rectified and filtered transformer input signal to a primary winding of a transformer. The secondary winding thereof may comprise a first tap associated with the first output voltage and a second tap associated with the second output voltage, the first and second taps being configured to be selectively coupled to and uncoupled from an output of the power adapter. The output current drawn at the output of the power adapter may then be sensed. When the sensed output current is determined to have exceeded a predetermined threshold, the output of the power adapter may be switched from the first to the second tap by uncoupling the first tap from the output of the power adapter and coupling the second tap to the output of the power adapter.

摘要： A technique for controlling a power supply (70) with power supply control element (82) with a tap element. In one embodiment, a power supply regulator includes a power transistor (88) having first, second, third and fourth terminals (89, 91, 93, 94). A control circuit (83) is included, which is coupled to the third and fourth terminals (93, 94) of the power transistor (88). The power transistor (88) is configured to switch a current between the first and second terminals (89, 91) in response a control signal received from the control circuit (83) at the third terminal (93). A voltage between the fourth (94) and second terminals (91) of the power transistor (83) is substantially proportional to a current flowing between the first and second terminals (89, 91) when a voltage between the first and second terminals (89, 91) is less than a pinch off voltage. The voltage between the fourth (94) and second terminals (91) of the power transistor is substantially constant and less than the voltage between the first and second terminals (89, 91) when the voltage between the first and second terminals (89, 91) is greater than the pinch off voltage.
