Solid-state lighting designers are often asked to develop optimized drivers quickly, with a somewhat fluid suite of physical, electrical and environmental requirements. The LYTSwitch™-5 single-stage LED Driver IC family from Power Integrations is highly configurable and supports a comprehensive set of isolated and non-isolated topologies. These include safety-rated isolated flyback for ballast applications and non-isolated buck and buck-boost for low-cost lamps and bulbs. A choice of low-side or high-side switching enables designers to optimize for low EMI or for reduced inductor complexity.

LYTSwitch-5 achieves over 90% efficiency, 0.9 PF, less than 5% THD and ±3% current regulation accuracy over line, load, production variance, temperature and multiple topologies. LYTSwitch-5 is the most flexible, easy to use non-dimmable LED Driver for solid-state lighting applications below 25 W. Highly accurate CC regulation reduces the degree of overdesign required to guarantee compliance to lumen output standards from regulatory bodies such as the California Energy Commission (CEC) and ENERGY STAR®.
