Endicott Research Group introduced a new range of plug-and-play LED driver solutions with enhanced performance features for high-power, high-brightness mid-size LED-backlit displays.

The new “Smart Force” SFDMD Series is specifically designed for applications that require a small footprint with high efficiency and brightness stability over a wide input voltage range, such as medical patient monitors, POS, kiosk, ATM, gaming and GPS displays. Less than 5 mm high, with a footprint of only 2.782″ (70.66 mm) x 0.96″ (24.4 mm), the new SFDMD drivers enhance ERG’s existing SFDM (Mini) Series with an even wider input voltage range of 3-20V. They can be modified to work from 3.3V, 5V or 12V input voltage, with an LED string voltage of up to 38.5V and an output current drive of 30 mA x 6 strings. The onboard PWM dimming feature can generate a dimming ratio of up to 255:1 via an external 0-5V analog voltage, which is compatible with most controller cards on the market today. SFDMD Series modules operate at a very high efficiency, ~90%, the company says.

“Compared to our closest competitor’s module for driving mid-sized LCDs, the SFDMD Series offers a smaller footprint, a wider input voltage range, a higher string voltage, and a higher output current drive,” said Scott Barney, Director of Sales and Marketing at ERG. “And when it comes to dimming, our competitor’s module offers only 10:1 analog dimming compared to onboard PWM dimming up to 255:1 for the SFDMD Series.”

Pricing for ERG’s new Smart ForceTM SFDMD Series LED Driver modules is approximately $18.00 in 1,000-piece quantities. Delivery is typically 4 weeks A.R.O.
