One of the common challenges of solid-state lighting (SSL) is controlling the thermal environment. National Semiconductor’s thermal management solutions address this issue with a family of temperature sensors that compliment their high-brightness LED drivers. The product line includes analog temperature sensors, temperature switch and analog temperature Sensors, digital … [Read more...]
Ultrafast Submicron Thermoreflectance Imaging
K. Yazawa and A. Shakouri Baskin School of Engineering, University of California at Santa Cruz, California Both the miniaturization of electronic and optoelectronic devices and circuits and the increased operation speeds of electronic devices have exacerbated localized heating problems. Steady-state and transient characterization of temperature distribution in devices … [Read more...]
LED Controller with Active PFC Needs No Opto-Coupler
New isolated LED controller with active power factor correction (PFC) is specifically designed for driving LEDs from a universal input range of 90VAC to 265 VAC. The LT3799 is cost efficient and more reliable because it delivers a well-regulated current to the secondary side without using an opto-coupler, and it is also compatible with standard TRIAC in-wall dimmers. Read more … [Read more...]
