TC62D902FG TOSHIBA CDMOS Integrated Circuit Silicon Monolithic T C 6 2 D 9 0 2 F G Offline Isolated flyback LED Controller with PFC TC62D902FG 1. Feature This product is isolated fly back LED controller IC with the power factor correction function. A LED current that flows to the secondary-side of transformer is controlled by feedback primary-side of transformer. Therefore, the Photo coupler is not used. External parts can be decreased compared with a past isolated fly back system. Moreover, PFC function of one converter type is built into, and the power factor improvement is possible by few parts.
