IRVINE, Calif., April 24, 2007 (PRIME NEWSWIRE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of analog and mixed signal integrated circuits, has announced the addition of three new modules to its StayLit(tm) backlight inverter family which is designed to ensure safe operation of dual-lamp cold cathode fluorescent displays if one lamp fails.
Safe continued operation that avoids overdriving the remaining lamp, and that maintains dimming capability, is particularly useful in patient monitoring equipment, ATM machines, point-of-sale terminals and similar applications found in the medical, industrial and commercial markets.
Microsemi's StayLit inverter modules are designed for dual CCFL lamp LCD displays from 6.5 to 10 inches that use a common return wire. The three newest inverters:
-- LXMG1626-05-45(tm) for 8 to 10-inch displays with 5V input
supplies;
-- LXMG1626-12-46(tm) for 6.5 to 8-inch displays with 12V input
supplies;
-- LXMG1626-12-46(tm) for 6.5 to 8-inch displays with 5V input
supplies.
They join Microsemi's initial StayLit module, the LXMG1626-12-45(tm), which provides 12V input for 8 to 10-inch displays.
"Our StayLit modules allow peace of mind for customers who need their displays to keep working safely after one lamp fails and until service resources are available," said Steven Litchfield, Executive Vice President and Group President of Microsemi's Analog Mixed Signal Group.
"The modules are based on our highly integrated LX1691B(tm) backlight controller to which we've added StayLit's fault tolerant design and a fault output signal. They provide all the safety and protection features that Microsemi backlight technology is known for -- like output open and short-circuit protection, automatic strike-voltage regulation and timeout," he added.
The modules provide 3 Watts output per lamp (6W per display) and feature Microsemi's patented RangeMax(tm) digital dimming technology for wide-range flicker-free brightness control. Typical dimming ratio is 100:1+.
PanelMatch(tm) circuitry permits easy external programming of the output current, a feature allowing Microsemi modules to fit a wide range of displays, simplifying the customer's supply chain.
The new modules measure 113mm long by 30mm wide and 6.5mm high. Their design supports a 5V or 12V input supply voltage and are rated for -30 to 80 degrees centigrade operation. All are RoHS compliant and are UL-certified components to UL60950 (file E175910). The modules mate to JST BHR-04-VS-1, or equivalent, connectors.
Information regarding StayLit module samples, pricing and lead times is available through Microsemi sales representatives and authorized distributors. For 50 pieces, the unit price is $39.95. Product data sheets and overview information that can match StayLit inverters to specific LCD displays are available on the Microsemi web site: www.microsemi.com.
