Dimmable High Voltage Direct AC LED Driver

LSI-LS9100LSI/CSI has announced the availability of a powerful, all inclusive new system level, High Voltage LED Dimmable Driver IC.† Designated†LS9100 Archimedes Series, this high-performance, low cost IC has a rugged design optimized for driving LED banks directly from the main utility line which eliminates the previously required, expensive and bulky AC-DC Power Supplies formerly used to drive LEDs.

The LS9100 has integrated a full bridge rectifier, current limiter source protection circuit, built-in thermal protection feature centrally located in the device that protects the IC from operating in atypical conditions, and a voltage shutdown circuit which safeguards the IC and the systemís LEDs from line voltage surges that can overstress the system, all on a single IC. By merging these features into an IC, the†LS9100†enables luminary designers to make LED luminaries with designs that are unconstrained by the size and bulk of the previously required Power Supply.
