In the following slideshow, iWatt Inc. (Campbell, Calif.) has introduced the iW3616 (12W) and iW3617 (25W) LED driver ICs based on the company’s third-generation digital AC/DC SSL LED driver platform. The drivers are designed for 120V/230VAC offline LED lighting bulbs and fixtures.
iWatt said the third-generation platform builds on iWatt’s previous-generation Flickerless LED driver, the 15W iW3614, increasing output power to 25W, lowering the bill of materials (BOM) cost by 10 percent to 20 percent, and expanding dimmer compatibility to ensure compatibility with installed dimmers, including residential TRIAC dimmers as well as the more sophisticated digital dimmers.
iWatt claimed its Flickerless technology achieves high power factor ( > 0.95), low total harmonic distortion (< 15 percent), and efficiency of over 85 percent.
Calling this a "design article" is a bit of a stretch isn't it? Lots of single-page ads are more "educational" than this. But from a marketing guy's perspective, this is a cheap way to get an ad in front of engineers. But let's call it what it is, please.
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.
