  Power Integrations Announces New Reference Design for Efficient PAR38 LED

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

Business Wire

SAN JOSE, Calif. -- August 27, 2013

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
LYTSwitch^TM-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 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.

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
