PI Adds High-Line Parts to LYTSwitch-4 LED-Driver IC Family

November 19th, 2013

Power Integrations today added devices optimized for high-line applications, completing the roll-out of its LYTSwitch™-4 LED-driver IC family. LYTSwitch™-4 ICs deliver accurate output current and high efficiency for bulb and tube applications and high-bay lighting. The devices simplify design and reduce cost while ensuring that lamps deliver uniform light output and provide exceptional performance in TRIAC-dimmable applications.

Designs based on the new drivers easily meet EN61000-3-2C regulations for total harmonic distortion (THD); optimized designs deliver less than 10% THD. Regulation is better than +/- 5% across load and production spread. The devices’ high switching frequency (132 kHz) enables smaller, lower-cost magnetics to be used, and frequency jittering reduces EMI filtering requirements. These factors enable LED-driver designs to fit easily into space-restricted bulb styles.
