Typical Application


Description

  The SSL5231T 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 5W lamp power like Candela shape up to 25W 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
