Power
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.”
