Behind The Bright Lights, LED Drivers Evolve
To Meet New Requirements By Randall Restle, Newark
high-brightness LEDs can generate usable levels of light with
improved efficiency, longer lifetimes, and smaller dimensions than
conventional light sources. Accurate current control is essential for an
effective LED lighting solution, and a wide variety of LED driver ICs is
available to help engineers optimize their designs.
Broadband Filter/ADC Driver Family Sports High
Accuracy
A family of five single and dual low-pass active
filter/analog-to-digital converter (ADC) driver amplifier devices from
Linear Technology Corp. provides high performance and wide bandwidths.
Overvoltage Protection IC Reduces Board Space
By 40%
Available in a 3- by 4- by 0.9-mm QFN-22 package, the NUS6189
promises to reduce board space by up to 40% by integrating four separate
protection functions.
The DS4560 self-protected, resettable hot-plug switch promises to
reduce the number of components necessary for the safe insertion and
removal of systems on 12-V backplanes.
