Beschreibung

This manual describes the performance, technical data and connection of the SSL5101DB1224 20 W flyback high-power factor universal mains demo board.

The SSL5101T is a highly integrated switching mode LED controller which enables constant current driving from the mains input. It is a solution for small to medium LED retrofit lamp applications. It can be optimized for high-power factor requirements.

The SSL5101T is a flyback converter controller suitable for isolated, non-dimmable LED retrofit lamps. It can drive long LED strings with up to 40 V forward voltages (typical).

The SSL5101DB1224 demo board is intended to operate with high output voltages, as present in modern LED modules.
