Microsemi Corporation , a manufacturer of analog/mixed signal integrated circuits and semiconductors, announced the expansion of its line of complete high performance system solutions for powering light emitting diode (LED) backlit displays. The family now includes 3-string applications for 3.5 inch to 7-inch displays.
The new modules, designated LXMG1930-28(tm), join Microsemis recently introduced LXMG1960-28(tm) high performance LED driver modules for 6-string applications. Together, the modules form a family that gives designers of medical, point-of- Sale (POS), kiosk, ATM and lottery terminals a choice of easy "plug and play" options for their applications.
Based on Microsemis LX1996(tm) LED driver integrated circuit, the new module family offers high performance features including 1 percent string-to-string current matching for optimum panel brightness uniformity, a wide 4.75V-28V input voltage capability, multiple dimming options with Ratios up to 1,000:1, and safety protection against LED shorts, over-voltage and over-temperature operation.
