Power Integrations has completed the rollout of its LYTSwitch-4 LED driver IC family with new devices optimised for high-line applications. The devices ensure that lamps deliver uniform light output and provide high performance in TRIAC-dimmable applications.
LYTSwitch-4 ICs feature a combined PFC (power factor correction) and CC (constant current) single-stage converter topology resulting in a power factor greater than 0,95 and efficiencies of over 90% in typical applications. Designs based on the new drivers easily meet EN61000-3-2C regulations for total harmonic distortion (THD), with optimised designs delivering less than 10% THD.
Regulation is better than ±5% across load and production spread, reducing the need for over-design to meet minimum luminance targets. 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.
Designers can evaluate the new LYTSwitch-4 LED-driver IC family using a new high-line LED lighting reference design that has been co-developed with Cree.
