Power Integrations Announces New Reference Design for Efficient PAR38 LED Spotlight

DER-350 achieves excellent dimming performance for all TRIAC dimmer types

SAN JOSE, Calif. — (BUSINESS WIRE) — August 27, 2013Power Integrations (Nasdaq: POWI), the leader in high-efficiency, high-reliability LED driver ICs, today announced a reference design for a dimmable PAR38 spotlight, developed in collaboration with Cree, Inc. (Nasdaq: CREE), a leading LED lighting company. The new reference design, described in DER-350, uses Power Integrations’ new LYT4317E, a member of the company’s LYTSwitchTM-4 family of single-stage drivers, along with Cree’s MT-G2 EasyWhite® 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 LYTSwitchTM-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 LYTSwitchTM-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.

Comments Andrew Smith, product marketing manager at Power Integrations: “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.” Adds David Cox, Cree’s director of alliance development: “ 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.”
