Cree and Power Integrations Collaborate to Develop Efficient PAR38 LED Spotlight

Power Integrations today announced a reference design for a dimmable PAR38 spotlight, developed in collaboration with Cree, Inc. The new reference design, described in DER-350, uses Power Integrations' new LYT4317E, a member of the company's LYTSwitch-4 family of single-stage drivers, along with Cree's MT-G2 EasyWhite(R) LEDs.


DER-350 includes an isolated, high-power-factor, TRIAC-dimmable LED driver optimized to deliver an LED current of 550 mA at 36 V (nominal) from an input voltage range of 90 VAC to 132 VAC. The combined PFC and CC single-stage, isolated topology of the LYTSwitch(TM)-4 IC delivers excellent efficiency, power factor of 0.98, and low component count. Over-voltage, overcurrent and over-temperature protection features are built-in.


DER-350 also showcases the LYTSwitch(TM)-4 IC's excellent TRIAC dimming with very fast sub-200 ms start-up, reduced pop-on and no dead-travel, easily satisfying NEMA dimming curve requirements, for both leading-edge and trailing-edge dimmers.


Product marketing manager at Power Integrations Andrew Smith says "The combination of the high lumen output, excellent optical control and color consistency of Cree's MT-G2 EasyWhite LEDs makes it ideal for directional luminaires such as the PAR38 replacement lamp." Cree's director of alliance development David Cox adds that "Power Integrations' low-cost, high-efficiency drivers complement our LEDs and facilitate designs that are compact, require little heatsinking and provide excellent dimmability. The result is LED-lighting solutions that are being readily accepted by customers."
