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.

摘要： A switching power converter for converting an AC power into a DC power. The converter includes a transformer, a charge storage unit, a synchronization signal generator, and a switch element. The transformer includes a primary side coil and a secondary side coil, and the primary side coil generates an induced voltage at the secondary side coil according to AC power. The charge storage unit charges according to the induced voltage and outputs a DC power. The synchronization signal generator generates a synchronization signal according to the induced voltage. The synchronization signal is the first value when the induced voltage is positive and is the second value when the induced voltage is negative. The switch element, serially connected to the secondary side coil and controlled by the synchronization signal, is turned on when the synchronization signal is the first value and is turned off when otherwise.

摘要： A low acoustic noise solution for snubber circuits is utilized for relieving spike noise under a low-load mode of a snubber circuit, and for avoiding electromagnetic interference under a high-load mode of said snubber circuit. A power transform device utilizing the low acoustic solution includes a power source node, a switch node, a ground node, a transformer, a third switching unit, a first spike noise snubber circuit, a first switch unit, a second spike noise snubber circuit, and a second switch unit. When the power transform device is under the low-load mode, the first spike noise snubber circuit is used to absorb power discharged from the transformer so that spike noise is relived. When the power transform device is under the high-load mode, both the first and the second spike noise snubber circuits are used to absorb power so that electromagnetic interference is relieved.
