This SMPS controller IC, equipped with fly-back control and integrated PFC, delivers highly efficient, flexible operation in a small form factor, and is ideally suited for indoor and outdoor SSL applications above 25 W.

 

The SSL1750 delivers very efficient power conversion from the universal mains. As a result, the IC generates less heat and thus maximizes efficiency. The very high level of integration reduces the number of external components and lowers overall cost.

Accurate current control through the LED’s makes it possible to dim the lights for additional energy savings. This is particularly useful in outdoor applications, since it means that the lights used along streets, in tunnels, or around parking areas can be dimmed when no one is around.

The integrated PFC controller meets the required power factor and harmonic distortion regulations for applications above 25 W.

• Operates from universal mains supply (80...276 VAC)
