Zusammenfassung:	A slim and cost effective power module solution derived from the multiple-phase buck converter technology that addresses the problems of inductor thickness and excessive magnetic material use. Such power module solution utilizes a multi-phase constant current topology and a corresponding electronic controller to provide a constant current source for various OLED lighting applications. The multi-phase constant current topology comprises two or more inductor-flyback diode feedback loops. Each inductor-flyback diode feedback loop is triggered ON and OFF out-of-phase by a current controller, which senses and estimates the average current supplied to the load, and causes the adjustments to the average current supplied to the load by controlling the ON duration of the inductor-flyback diode feedback loops.
