Rogers Corp. expanded its DUREL integrated driver product line with the release of the D381B electroluminescent (EL) driver module. According to the company, the D381B driver is another "stand-alone" EL driver module solution that combines all external, discrete components required to backlight monochrome displays and keypads into a single, cost-effective chip.

"Because their BoM are reduced by seven components, our customers prefer our modular drivers—it simplifies their inventory and purchasing process," said Rob Kimball, business development manager of the Durel Division of Rogers. "As with our other integrated drivers, the D381B module cuts down on the number of suppliers from four to one while providing ease of design and assembly."

The 5-by-7mm D381B driver has a power inductor already imbedded inside the module. It operates with a wide DC input voltage range (2V to 6V) to fit various types of electronic applications and battery technologies, and delivers high efficiency that is well suited for wireless communications devices, such as PDAs, handsets and other electronic applications.

In addition, the D381B integrated module utilizes Rogers' patented three-port (3P) topology for reduction of audible and electrical noise, and features internally controlled current discharge for additional reduction of audible and electrical noise.

Like other Rogers EL drivers, the new D381B module is RoHS and WEEE (Waste of Electric and Electronic Equipment) compliant. Samples of the Pb-free D381B module are available from stock.
