PARIS – iWatt Inc announced it has introduced a digital AC/DC LED driver platform, and the first device is a two-stage, Flickerless LED driver with output power up to 45W.
The company (Campbell, Calif.) claims the iW3630 has a built-in 0V to 10V dimming interface for commercial lighting ballasts and supports a PWM digital dimming interface for wireless SSL applications.
iWatt said the iW3630 SSL LED driver is the first in a platform designed to address cost, performance and operating life in 0V to 10V commercial lighting systems. It is a two-stage, Flickerless LED driver with output power up to 45W and an integrated design that is claimed to enable a 30-percent to 40-percent savings in BOM cost compared to competitive solutions in 0V to 10V applications.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
