The SSL5261PT is part of a new range of LED driver ICs for non–isolated, 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.

• Supports majority of available dimming solutions
• Deep dimming level
• Flicker-free dimming
• Peak dimming control
• Low electronic Bill Of Materials (BOM) ensuring a compact solution and small,single layer Printed-Circuit Board (PCB) footprint
• Flexible buck or buck-boost applications using external power FET
