TRIAC-Dimmable LYTSwitch-7 LED Driver ICs From Power Integrations Cut BOM Count by 40%

Bleeder-less, highly efficient, robust IC family serves bulbs, tubes and fixtures up to 22 W

Power Integrations (Nasdaq:POWI), the leader in high-efficiency, high-reliability LED driver ICs, today announced its LYTSwitch™-7 single-stage, non-isolated, TRIAC-dimmable, buck topology LED driver IC family. Capable of delivering up to 22 watts without a heatsink in a very small SO-8 footprint, these high-efficiency devices are suitable for bulbs, tubes and fixtures. LYTSwitch-7 designs do not require bleeders; employing simple, passive damping for TRIAC management and an off-the-shelf, single-winding inductor, reducing component count to just 20, as compared to approximately 35 parts for typical dimmable LED driver boards.

LYTSwitch-1 LED Driver ICs From Power Integrations Reduce Complexity in Bulbs, Tubes and Ballasts up to 22 W

High PF, low THD LED driver ICs set a new standard in efficiency

SAN JOSE, Calif.--(BUSINESS WIRE)-- Power Integrations (Nasdaq: POWI), the leader in high-efficiency, high-reliability LED driver ICs, today announced its LYTSwitch™-1 single-stage, non-isolated, buck topology LED driver IC family. Featuring a very compact footprint, the IC enables the design of LED bulbs and tubes with high constant-current accuracy while using a minimum number of components. A novel driver algorithm ensures high power factor (PF) and low total harmonic distortion (THD) while maintaining very high efficiency.
