Microsemi's Unique RangeMax(tm) and PanelMatch(tm) Feature Set Now Available in New CCFL Inverter Products
Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, today announced the availability of its cost optimized family of high performance CCFL backlight inverters for dual lamp LCD panels.
The new inverter family is designed to migrate Microsemi's proven, IP-differentiated backlighting technology developed to meet demanding automotive, LCD TV and notebook applications into a broad range of mid-sized panel designs, by delivering cost-to-feature benefits of outstanding reliability, efficiency and service. The new inverters will enable Microsemi's leading backlighting technology to be used in many 7- to 19-inch panel applications including medical, POS, kiosk, ATM, and lottery terminals. Inverters identified by product numbers LXMG1627 offer Microsemi's patented RangeMax(tm) digital dimming technology, while those numbered LXMG1628 provide analog dimming.
"Customers who are designing many mainstream applications continue to demand the proven reliability and cost competitiveness offered by CCFL backlighting. We're committed to support our customers with complete high-performance backlight solutions at affordable prices for these embedded applications," said Irene Signorino, director of marketing at Microsemi's Analog Mixed Signal Group. "Microsemi backlight management expertise is now available for single, dual and quad lamp CCFL backlit panels through our CCFL ICs and our expanded portfolio of cost optimized plug-and-play inverter modules." In addition to CCFL backlight solutions, Microsemi supports LED backlit panels through its family of LED driver ICs. Both CCFL and LED IC drivers are further enhanced by the company's complementary line of light sensors and color management blocks.
KEY FEATURES:
- PanelMatch(tm) provides custom lamp current settings and simplifies supply chain management when multiple panels are used (perfect for distributors and integrators)
- RangeMax(tm) digital dimming (LXMG1627) and analog dimming (LXMG1628) versions enhance user experience and extend lamp and battery life
- Extended operating temperature range from -30 degrees C to +80 degrees C
- Compact direct drive design
- Reliable and robust designs with calculated MTBF of 100 years or more
- RoHS, UL certified components, UL60950 E175910
- 5V (digital dimming only) and 12V input supply voltage, 4W and 6W maximum power outputs
- Available with JST BHR-03VS-1, BHSR-02VS-1 output connectors or equivalent
BENEFITS:
- PanelMatch(tm) increases the customer supply chain effectiveness since the same Microsemi inverter can be used to drive panels with significantly different lamp current (up to 1mA step, 3mA maximum difference).
- RangeMax(tm) digital dimming technology provides smooth, jitter free, wide-range brightness and advanced power management capability and reduces cost of ownership for the end system. This technology is proven to extend the lamp life as measured by light output at the end of the time period compared to the more standard amplitude adjustment method. The life extension depends on the dimming ratio used by the customer. A 100:1 digital dimming ratio can provide an 80-90% increased light output after 20k hours. Since the lamp is usually the first component needing replacement in a panel, this translates into direct ownership and warranty cost savings.
- The direct drive design allows for a more compact, smaller and efficient solution compared to other topologies
- The new dual lamp inverters, designed according to stringent Microsemi design rules and qualification requirements, have a calculated MTBF of approximately 100 years. All are UL certified components per UL60950 file E175910.
The new CCFL inverter modules are supported by Microsemi's recently announced eight-week lead time availability for its most popular inverters.
