NXP Semiconductors N.V. is adding to the company's broad
GreenChip SSL family of products, the GreenChip SSL4101T controller IC,
which offers new levels of professional-grade performance for Solid
State LED lighting power supplies. The GreenChip SSL4101T enables LED
lighting for medium to high power commercial and professional
applications with industry-leading performance in Total Harmonic
Distortion (THD) of less than 20 percent, a high Power Factor (PF) of
.99, and high efficiency of 94 percent.
The GreenChip SSL4101T is based on NXP's high voltage process and
enables direct start-up from the rectified universal mains voltage in an
effective, eco-friendly way. The multi-chip module contains both a
flyback controller and a controller for Power Factor Correction, and
provides high efficiency at all power levels. The new GreenChip SSL4101T
is ideally suited for LED lighting applications that require a very
efficient, low THD, high PF, true universal input voltage and
cost-effective power supply solution ranging between 10 W and 300 W.
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.
