Phoenix, Ariz. – ON Semiconductor has introduced the CAT3661, a one-channel quad-mode LED driver for low power LED applications such as portable handheld medical equipment.
The CAT3661, which uses a patented architecture and integrates fault protection and diagnostics, is able to drive a single LED backlight with a current of up to 5 mA. Soft-start current limiting and short-circuit protection make the device suitable for use in equipment powered by coin cell batteries. Typical applications include low power backlighting for LCDs and backlighting for a wide range of portable handheld devices including medical equipment.
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.
