Abstract: A power bank device includes a load node, a power-supply circuit, an output circuit, a detecting unit, and a control circuit. The power-supply circuit provides an output current via the load node. The output circuit generates an output voltage at the load node according to the output current. The detecting unit generates a detecting signal according to the output current. The output circuit includes an impedance circuit. The control circuit, according to the detecting signal, controls the output circuit to switch an impedance of the impedance circuit, thereby down-regulating the output voltage and the output current.

Abstract: The present invention relates to a driving circuit of LED and a driving method thereof, which comprise a converting circuit and a driving unit. The converting circuit receives a pulse-width modulation (PWM) signal and generates an adjusting current according to the PWM signal. The driving unit receives the adjusting current and generates at least a driving current according to the adjusting current for driving a plurality of LEDs coupled to the driving unit. The magnitude of the driving current is adjusted according to the adjusting current. In addition, the driving unit has a bright-controlling pin used for receiving a control signal having a fixed level.
