Power Integrations has joined forces with Cree to develop four reference designs describing drivers for dimmable PAR 30 and PAR 38 LED light bulbs showcasing PI’s LYTSwitch-4 driver ICs and Cree’s MT-G2 EasyWhite LEDs.
DER-364 and DER-365 detail low- and high-line PAR 30 LED bulb drivers, respect-ively, while DER-350 and DER-396 address low- and high-line PAR 38 bulbs.
LYTSwitch-4 ICs deliver accurate output current regulation in bulb and tube replacement applications and high-bay lighting. They are well suited to TRIAC-dimmable applications and combine power factor correction and constant current in a single-stage topology, resulting in power factor greater than 0,95 and typical efficiencies of better than 90%.
The single-stage approach also eliminates temperature-sensitive electrolytic bulk capacitors, greatly increasing the bulbs’ reliability and lifetime. LYTSwitch-4 ICs also operate at a high switching frequency (132 kHz), enabling smaller, lower-cost magnetics to be used, while frequency jittering reduces the need for EMI filtering. These factors combine to deliver LED-driver designs that fit easily into space-restricted bulbs.
