Power Integrations (San Jose, CA) recently introduced the RDR-347, an LED-downlight reference design. The new circuit demonstrates the capabilities of the recently launched LYTSwitch™ IC family, which offers high-end dimming performance from a singlestage LED driver.

The RDR-347 12 W reference design, based on the LYT4313E, delivers a power factor greater than 0.95 and reduces total harmonic distortion (THD) to less than 10% - easily meeting EN61000-3-2C requirements. Efficiency is greater than 86% at 120 VAC. The LYTSwitch ICs use one combined PFC and CC power conversion stage.
