摘要： A power adaptor includes an inverter, a feedback circuit, a detecting unit, and an adjusting unit. The inverter is configured to convert an input voltage into an output voltage according to a power conversion ratio and adjust the power conversion ratio according to a feedback voltage. The feedback circuit is configured to provide the feedback voltage by voltage-dividing the output voltage according to a specific ratio. The detecting unit is configured to detect a load of an output end of the power adaptor. The adjusting is configured to adjust the specific ratio according to the loading variation of the load.

摘要： A power system having a power saving mechanism includes a voltage regulator, a power input module, and a switching signal generation unit. The voltage regulator performs a regulation operation on a first voltage for generating a second voltage. The power input module includes a transformer, a rectifying unit, a switch, and a switch control unit. The rectifying unit together with the transformer is put in use for converting an input voltage into the first voltage. The switch is employed to control a current flowing through the primary winding of the transformer. The switch control unit generates a control signal for controlling the switch according to a switching signal. The switching signal generation unit is utilized for generating the switching signal to disable the switch control unit during an energy transfer disable interval so as to decrease the first voltage from a first predetermined voltage to a second predetermined voltage.

摘要： In order to provide open-lamp protection to a backlight module, a pseudo open-lamp voltage is first generated according to the current flowing through a light source. If the backlight module receives a mode signal corresponding to a high contrast mode, a compensation voltage is added to the pseudo open-lamp voltage for generating a reference voltage. If the reference voltage is larger than a feedback voltage received from an input node of the light source, a driving voltage is outputted to the light source.
