產(chǎn)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.
