Microsemi Adds Two PanelMatch Modules For Powering Four-Lamp LCD Displays
-- Programmable Output Simplifies Customer Use in Multiple Applications
IRVINE, Calif.--(BUSINESS WIRE)--Sept. 24, 2002-- -- Target High Brightness, Desktop, Industrial Displays
Microsemi Corp. (Nasdaq:MSCC - News), a leading manufacturer of power management integrated circuits, today announced the addition of two new four-lamp PanelMatch(TM) models to its lineup of inverters used to power cold cathode fluorescent (CCFL) lamps in display panels.
Designated the LXM1643(TM) and LXM1644(TM) modules, they join Microsemi's single and dual-lamp PanelMatch offerings -- each designed to allow customers to use a single device more easily in multiple applications, thus saving design time and reducing parts inventory. The two new modules target 12-inch to 18-inch panel displays found in desktop computers, high-brightness screens and industrial control displays.
Key to the unique PanelMatch design is its externally programmable maximum output current capability over a range from 5 to 8 mA per lamp. This allows customers to match these Microsemi inverters, in 1mA steps, to a wide array of LCD panel lamp current specifications.
"With the addition of our two newest PanelMatch modules, Microsemi now offers off-the-shelf solutions that greatly simplify customer design-ins for panels all the way from 3.9 to 18.1 inches in size and from one to four lamps," said Kelly Jones, senior vice president and general manager of Microsemi Integrated Products.
"Their programmable output power matching capabilities solves the common customer problem of having to find new inverters any time a panel manufacturer changes specifications," he said.
The LXM1643 is a 12V/24watt quad inverter designed for thin film transistor (TFT) applications requiring wide-range dimming. For these applications, Microsemi provides a 50:1+ dimming ratio with its patented RangeMAX(TM) direct drive digital dimming technology that uses controlled power bursts for flicker-free dimming and power savings. This inverter includes a dimming input to control brightness from a DC voltage source, a PWM signal or external potentiometer.
The LXM1644 is a 12V/24watt quad inverter using conventional current amplitude dimming where a dim ratio of only 5:1 is suitable. It also has a dimming input available to control brightness from a DC voltage source, a PWM signal or external potentiometer. This module is targeted at lower-cost super twisted nematic (STN) panels or TFT applications requiring little or no dimming.
Both modules are intended for panel assemblies where lamp pairs share close proximity with one another. The LXM1643 also has a version for applications having four individual lamp connections, or where the lamps are spaced well apart from each other.
Microsemi's highly integrated controller design eliminates as many as 30 components in all PanelMatch modules, while providing cost and performance advantages that include stable fixed-frequency operation, secondary-side strike-voltage regulation, open and shorted lamp protection with fault timeout, and an extended temperature rating of -20(degrees)C to 70(degrees)C.
The LXM1643 and LXM1644 PanelMatch modules are available for immediate sampling and delivery, with 10K quantity pricing from $27.69 for the wide-range dimming inverter and $24.92 for the LXM1644.

Samples can be ordered through this site, or from Microsemi sales representatives and franchised distributors.
