The SSL5255TE is part of a new range of LED driver ICs for nonisolated, dimmable (phasecut dimmable or with a control input signal) LED solutions. Complementing NXP’s broadGreenChip SSL family of products, the new IC supports LED lighting applications rangingfrom 5 W lamp power like Candela shape up to 25 W lamp power like integratedFixtures/Luminaires, TLED and PAR lamp shapes.
