Title:
HIGH FREQUENCY LED DRIVER, THREE DIMENSIONAL INDUCTOR AND METHOD OF MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2011/146427
Kind Code:
A3
Abstract:
A driver device for driving an LED lighting device includes at least one power switch adapted to operate at a switching frequency of greater than 500 KHz and adapted to control the driving current provided to the LED lighting device. Operating the power switch at such a high frequency allows a substantial reduction in passive devices such as inductors and capacitors. Also, an integrated 3-dimensional inductor device is provided. The inductor device includes a substrate having an electrical trace and a 3-dimensional inductor attached to the substrate. The inductor includes a magnetic core and a coil whose windings are formed from the electrical traces of the substrate and conductive material in the interconnect vias.
