SSL5261AT中文资料Compact high power factor dimmable LED driver IC (v2)数据手册Silergy规格书

描述 Description

The SSL5261AT is part of a new range of LED driver ICs for nonisolated, dimmable (phase cut dimmable or with a control input signal) LED solutions. Complementing NXPs 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.
