SSL525x - Compact high power factor dimmable LED driver ICs (v2) - 交流供电LED驱动器IC - 可调光 - 照明驱动器和控制器IC - 恩智浦, LLC
产品描述
The SSL525x is a family of LED driver ICs for non–isolated, dimmable (phase cut dimmable orwith a control input signal) LED solutions. Complementing NXP’s broad GreenChip SSLfamily of products, the new IC supports LED lighting applications ranging from 5 W lamppower like Candela shape up to 35 W lamp power like integrated Fixtures/Luminaires, TLEDand PAR lamp shapes.
