Typical Application
Description
The SSL5261PT is part of a new range of LED driver ICs for non–isolated, dimmable (phase cut dimmable or with a control input signal) LED solutions. Complementing NXP’s broad GreenChip SSL family of products, the new IC supports LED lighting applications ranging from 5 W lamp power like Candela shape up to 25 W lamp power like integrated Fixtures/Luminaires, TLED and PAR lamp shapes.
Applications
- Low cost mains dimmable, non-isolated retrofit LED lamps up to 25 W
- Low cost mains dimmable, non-isolated driver modules for LED lighting up to 25 W
