SFDM (Mini) Series LED Driver board for LED-backlit displays provides a full
function power supply with
optimum power for high brightness as well as lower power consumption and lower
cost in an exceptionally compact size - 1.11 inch (28.2 mm) x 3.10 inch
(78.7 mm), and less than 5 mm high. It
provides brightness stability over a wide input voltage (8-20V), with external
PWM (pulse width modulation) dimming to 250:1, can power up to 6 LED strings, and is compatible with virtually
all OEM LED-backlit panels. Use of high-bright
LEDs in LCD backlights creates new challenges for the power supply driving the
LED BLU (backlighting unit). Getting optimum performance from LED BLUs requires
a full-function power supply that maintains a constant current, providing
sufficient voltage across the LED BLU to light the LED strings and provide
proper current regulation. The challenges facing power supplies (i.e., drivers)
for LED-backlit displays cannot be met by the many single-chip IC drivers
available on the market The SFDM is designed to
account for this voltage change and can light across the entire normal
operating range of temperatures, with no time or expense devoted to designing a
boost circuit. The SDFM Driver board can also be used with ERG's Smart ForceTM
LED rails. These are special rails that utilize a proprietary new design
to provide thermal management superior to any other technology on the market.
The thermal management technology utilized inside the rails addresses the major
challenge for LED BLUs: keeping the LEDs cool.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
