IRVINE, Calif., Feb. 26, 2008 (PRIME NEWSWIRE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog and mixed signal integrated circuits and high reliability semiconductors, has announced a new feature-rich multi-string LED driver for notebook computer-sized displays to its broad portfolio of LED and CCFL backlight controllers.
Designated the LX1996(tm), Microsemi's newest controller is designed to drive up to six strings of white LEDs that are used in mid-sized displays found in notebooks and monitors, entertainment systems and automotive applications.
"In addition to what we believe to be the most precise current matching, highest efficiency and fastest response driver in the industry, our new LX1996 features panel temperature compensation of LED current to help extend lamp longevity," said Steve Litchfield, Microsemi Executive Vice President and Analog Mixed Signal Group President.
The new driver provides +/- 0.5% current matching and is designed for applications having input voltage ranging from 6.0V to 28V and LED strings of up to 10 LEDs at 30 mA per string. It operates in temperatures from -40 degrees C to +85 degrees C.
Among its advanced features are a direct ambient light sensor interface for brightness control, multi-mode dimming options using PWM and/or analog signals that can deliver up to a 25,000:1 dimming ratio, ultrasonic pulse skipping for audible noise reduction, low standby current and safety protection including on-chip thermal shut-down, over-voltage protection, opened and shorted LED protection.
Packaged in a thermally efficient 24-pin MLPQ package that's only 4mm square, the LX1996 LED driver is unit priced at $0.75 in 10K quantities.
