摘要： A current-sharing power supply apparatus is applied to regulate voltage level of an input DC voltage, and the regulated DC voltage is stabilized in a predetermined voltage to be used on rear-end circuits. The current-sharing power supply apparatus includes a square-wave generating circuit, a rectifier circuit, a conversion circuit, a rectifier circuit, a filter circuit, a first output terminal, and a second output terminal. The current-sharing power supply apparatus provides two output voltages with a multiple relation from the first output terminal and the second output terminal, respectively.

摘要： A light emitting diode (LED) driving device is used to drive an LED module. A conductive current flows through the LED module when the LED module is driven. The LED driving device includes a driving-controlling unit and a current-regulating unit. The driving-controlling unit is driven by a controllable current. The current-regulating unit is electrically connected to the LED module and the driving-controlling unit. The current-regulating unit divides the branch of the conductive current into two branches, and controls the current flowing through one of the branches to be proportional to the controllable current. Therefore, the current-regulating unit provides a stable current to the driving-controlling unit and prevents the driving-controlling unit from an overcurrent damage.
