Smart Bridge module facilitates transition to LED backlit LCD

June 06, 2012 // By Christoph Hammerschmidt
ERG's Smart Bridge module resolves some of the problems users are currently experiencing by using the system's existing input power signals and converting the analog dimming signal used for the inverter into a PWM signal for the LED driver. In this way, the system's existing signals are utilized, powering the LED backlight driver without additional modifications.

Accordig to the vendor, it is very easy to exchange the existing part by the Smart bridge: Remove the inverter, plug in the footprint-compatible Smart Bridge module, and connect the input cable from the existing power supply or controller to the Smart Bridge. The Smart Bridge module converts the Power · Ground · Enable · Control signals and mates directly to the LCD via a small harness, powering the new backlight driver correctly. This avoids the time-consuming and expensive alternative of system re-design.

ERG currently offers three versions of the Smart Bridge module. The standard version ( SBD4212F) is a Smart Bridge Pass-Through with Integrated PWM Dimming and operates from a typical 12V signal. The Smart Bridge DC-DC Converter with Integrated PWM Dimming ( SBDCD4213F) is designed for applications requiring a step-up conversion from 5V to 12V. The third version is the Smart Bridge DC-DC Converter Without Dimming ( SBDC4227F). The Smart Bridge modules are available in the footprint of most inverters, and custom footprints are available.
