LYTSwitch

The LYTSwitch Family of highly integrated LED Driver ICs enable the design and production of LED drivers that use up to 70% fewer components compared to discrete solutions. LED drivers that incorporate LYTSwitch ICs are smaller, lighter, and more portable than comparable power supplies. In addition, LYTSwitch devices in both isolated and non-isolated topologies deliver the low THD required by today's lighting market, while safely meeting challenging line-voltage conditions. Finally, LYTSwitch products with dimming capability feature excellent compatibility and dimming range.
