Title: Power supply for a plurality of light emitting diodes

Abstract: A light emitting diode (LED) power supply providing current to a plurality of LEDs comprises a planar transformer. The planar transformer comprises a first multilayer printed circuit board comprising a first plurality of planar windings electrically connected in series to form a first primary portion. Each winding of the first plurality of planar windings is carried on a separate layer of the first multilayer printed circuit board. The transformer further comprises a second multilayer printed circuit board comprising a second plurality of planar windings electrically connected in series to form a second primary portion. Each winding of the second plurality of planar windings is carried on a separate layer of the second multilayer printed circuit board. The transformer additionally comprises a third multilayer printed circuit board comprising a third planar winding carried on two layers to provide a secondary.
