ROHM announced the availability of the latest LED driver IC, the BD81A76EFV-M, optimized for LCD backlight in instrument cluster, center information displays and car navigation. Unlike conventional drivers with 4 channels that support LCDs up to 8”, this IC provides 6 channels of output (with 120mA per channel) that can support LCD panels of up to 10-12” class. At the same time original buck-boost control ensures compatibility with both small and large LCDs using a single driver. This makes it possible to develop a common design of LCD control board suitable for conventional panels along with the latest large-size displays.

In recent years, to improve both visibility and design in the automotive field, LCDs are being used in an increasing number of systems including instrument clusters, head-up displays and car navigation. In addition, larger screen sizes are being demanded. They require a greater number of high brightness LEDs for backlight as well as LED drivers featuring multi-channel operation and advanced dimming features that can prevent flicker effects.

In response to this increasing market need, ROHM has leveraged its industry-leading analog design technology and incorporated proprietary technologies into its LED drivers to achieve flicker-free operation and to contribute to a common control board design. The BD81A76EFV-M also allows designers to use larger LCD panels in vehicle applications.
