摘要： The present invention discloses a switching regulator having a control circuit which includes an error amplifier circuit. The error amplifier circuit compares a feedback signal relating to an output voltage with a reference signal, to regulate the feedback signal to a level of the reference signal. When it is determined that the switching regulator has entered a shutdown procedure, the reference signal gradually decreases so that the output voltage is decreased to a shutdown threshold.

摘要： The present invention discloses a light emitting device array billboard and a row switch circuit and a control method thereof. The light emitting device array billboard includes a light emitting device array circuit, plural row switch circuits, plural column driver circuits, and a control circuit. The light emitting device array circuit includes plural light emitting devices arranged by columns and rows. Each row switch circuit determines whether to electrically connect a row conduction voltage to the corresponding row node or to discharge charges at the corresponding row node through a discharging path according to a row selection signal. Each column driver circuit determines whether or not to electrically connect a column conduction voltage to the corresponding column node according to a column selection signal. The control circuit provides the row selection signal and the column selection signal to the row switch circuits and the column driver circuits.
