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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
