This paper proposes a novel high power factor LED driver based on SY5800A for interior-lighting applications. High power factor is achieved by using the transformer with back winding coil and the transformer with “sandwich” winding coil. In addition, the proposed driver features cost-effectiveness, high circuit efficiency, low input current ripples and a reduced components count. A sample driver is developed to supply a 15W LED interior-lighting module with a 0.99 power factor. Experimental results demonstrate the functionalities of the proposed circuit.
