EL Driver Module
Rogers Corporation introduces the D381B electroluminescent (EL) driver module the newest addition to its DUREL® integrated driver product line. The D381B driver is a "standalone" EL driver module that combines all external, discrete components required to backlight monochrome displays and keypads into a single chip. This small, integrated driver module provides a turnkey solution for application designs as well as board mounting. The 5 × 7 mm D381B driver has a power inductor already embedded inside the module. It operates with a DC input voltage range (2.0 to 6.0 V) to fit various types of electronic applications and battery technologies. The D381B module’s high efficiency is suited for wireless communications devices, such as PDAs, handsets, and other electronic applications. The D381B integrated module utilizes the company’s patented three-port (3P) topology for reduction of audible and electrical noise. It also features internally controlled current discharge for additional reduction of audible and electrical noise.
