New Microsemi Single CCFL Lamp Modules
Description Upgraded & Improved Replacements of Existing LXMG1617 & LXMG1618TM
"A" Series: LXMG1617A & LXMG1618A
The new "A Series" modules are designed as a higher performance near drop-in replacement for those customers and applications currently using the LXMG1617 and LXMG1618 inverters.
"A" Series Dimming and Temperature Range Enhancements
The A Family modules will be offered in both a wide dimming version (LXMG1617A) and a standard dimming version (LXMG1618A). It integrates the newer highly integrated LX1691B CCFL backlight controller to provide wider dimming range (typically 100:1+) and wider temperature range (-30°C to 80°C) compared to the existing solutions (LXMG1617 and LXMG1618 families). Dimming RangeMax The modules include a dimming input that permits brightness control from a DC voltage source, a PWM signal or an external potentiometer (Universal Dimming Input). The patented "burst drive" that energizes the lamp (RangeMaxTM) was designed to ensure that no premature lamp degradation occurs, while allowing significant power savings at lower dim levels.
inverter with the feature called PanelMatchTM. These wide steps are made possible by custom settings on the module itself thus allowing the SAME module to be used to drive different panels (simpler supply chain and reduced inventory carrying costs specifically for solutions integrators and distributors or customers using multiple displays).
"A" Series LXMG1617A and LXMG1618A Specifications
Please always refer to the latest datasheet posted on www.microsemi.com. Products in development show Preliminary Specifications only. R.C. Recommended Operating Conditions. Full Bright Lamp Current (each lamp).
Cross-Reference Guide: Upgrading from Previous Modules to "A" Series
Availability: The new "A Series" modules will be available starting in November 2007 with full volume production from January 2008. Early sampling available, please contact your sales representative for details.
LXMG181x Series
The LXMG181X Series, available in 5V and 12 V Input, is an enhanced offering to run single CCFL lamp displays. It integrates the latest, most intelligent and efficient Microsemi CCFL ICs. Product Enhancements The LXMG181X Series is designed to enhance the current offering: the customer will benefit from a wider input voltage range (VIN) at Fully Regulated Lamp Current, and an enhanced Lamp Driving
capability (see the range of VLAMP and the Striking capability). Fewer part numbers (4 instead of 24) will be able to drive an extended list of displays thus greatly simplifying the customer supply change and minimizing the need of re-qualification and redesign of the backlight driving units in case a display is changed. Distributors and Integrators dealing with multiple displays will now be able to stock a lower number of parts to meet their needs.
Panelmatch As with the previous solutions customers will be able to externally program the output current in steps of 1mA with the feature called PanelMatchTM. These wide steps are made possible by custom settings on the module itself thus allowing the SAME module to be used to drive different panels (simpler supply chain and reduced inventory carrying costs specifically for solutions integrators and distributors or customers using multiple displays). Applications · Medical Displays · Portable and battery powered Instrumentation (specifically benefiting by automatic brightness adjustment for power savings obtained through the visible light sensor) · Industrial Display Control Benefits · Smooth, Flicker Free Full Range Brightness Control · Programmable Output Current allows the inverter to mate with a wide variety of LCD panels specifications · Output Open Circuit Voltage Regulation minimizes Corona Discharge for High Reliability and Efficiency · RoHS and UL Certified Components · Extremely simplified supply chain for Distributors and Integrators as well as end customers using multiple displays
LXMG181x Specifications
Availability The new LXMG1811 5V Series will be available starting in June 2008. The new LXMG1813 12V Series will be available starting in February 2008. Early sampling is available. Please contact your sales representative directly.
Microsemi LX1974 Visible Light Sensor
Internal temperature compensation allows dark current to be kept below 200nA over the full specification temperature range (-40 to +85°C), providing high accuracy at low light levels. Usable ambient light conditions range is from 1 to more than 5000 Lux. The LX1974 is optimized for controlling back lighting systems in low cost consumer products such as LCD TV, portable computers, and digital cameras. Key Features · Near Human Eye Spectral Response · Very Low IR Sensitivity · Highly Accurate & Repeatable Output Current vs. Light · Scalable Output Voltage · Temperature Stable · Integrated High Gain Photo Current Amplifiers · No Optical Filters Needed
