Smart Bridge module eases transition to LED backlit LCD

Easing the transition to LED backlit LCD, the Smart Bridge module uses a system’s existing input power signals and converts the analog dimming signal used for the inverter into a PWM signal for an LED driver.

The one swap process involves removing the inverter, plugging in the footprint-compatible Smart Bridge module and connecting the input cable from the existing power supply or controller to the Smart Bridge. The device converts power, ground, enable, and control signals and mates to the LCD via a small harness.

Three versions are available. The SBD4212F standard version Smart Bridge Pass-Through with integrated PWM dimming operates from a 12V signal. The SBDCD4213F is a Smart Bridge DC-DC converter with integrated PWM dimming, designed for applications that need a step-up conversion from 5V to 12V. The SBDC4227F is a Smart Bridge DC-DC converter without dimming. Priced from $9-$15 in production quantities. Contact company for availability.
