Abstract:
An exemplary power control circuit (24) includes a scaler circuit (245) configured for outputting a control signal, a voltage converter (27) configured for converting a received voltage into a plurality of desired voltages, a first control unit (28), a second control unit (29), and a coupling circuit (26). The first control unit is configured for controlling whether a first voltage is applied to the voltage converter. The second control unit is configured for controlling whether to transmit a second voltage applied thereto. The coupling circuit is between the first and second control units. The coupling circuit enables the second control unit to function ahead of the voltage converter according to the control signal.
