TDK-Lambda's second generation ALD6 series
of multi-output dc-dc backlight LED drivers are for LCD displays. Each ALD6
device can be used to backlight LEDs arranged in 1, 2, 3 or 6 string
configurations. The drivers feature wide-range dimming controls with resistive,
analog or PWM inputs for LED brightness transitions. The ALD6 has six outputs
and each provide up to 50mA of constant-current drive to strings of LEDs
connected in series and/or parallel configurations for backlighting LCD
displays. For a single-string LED configuration, the combined output current is
The ALD6 drivers operate with an input voltage of
from 10.8 to 13.2V dc and provide an output voltage of 25V to 38V dc. The single
package drivers are available in either DIP or SMD packages that measure about 23
x 21 mm.
Other features include a Remote On/Off input and an
LED Open Alarm that changes state if the drive current to any powered LED-string
develop an open circuit. These drivers are convection cooled and designed to
operate in ambient temperatures ranging from -30 up to +80C. The ALD6 can
provide 0 to 100 percent brightness control when an external PWM signal is
provided. The brightness will vary directly with the duty cycle of the PWM
signal. A combination of external analog or resistive and PWM dimming controls
can be accommodated.
The ALD6 Series are useful for backlighting LCD displays,
panels used in vending machines, industrial touch screens, POS terminals and
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
