Endicott, NYEndicott Research Group (ERG) has released two Smart Force LED driver boards for industrial LCDs.
Both provide full function LED drivers in a compact size, with wide range dimming, wide input-voltage, and full brightness and enable control. ERG also offers Smart Force LED Rails for use with the driver boards that use a proprietary design to provide thermal management.
The SFDL Series driver board provides high efficiency power (max. current 180 mA) to LED rails used in LCDs up to 12.1-in diagonal, with wide range dimming, wide input voltage and full brightness and enable control. It measures only 1.10-in. x 3.93-in. (27.9 x 99.8 mm), and is less than 8 mm high. It provides an onboard PWM dimming ratio of 1000:1 and external PWM dimming to 5000:1.
The SFDC Series driver board is a full-function LED driver (max. current 1000 mA) for high-power HBLED backlight rails used in LCDs up to 20.1-in. diagonal. It provides an onboard PWM dimming ratio of 1000:1 and external PWM dimming to a ratio of 20,000:1. It measures 1.10-in. x 5.61-in. (27.9 x 142.5 mm), and is less than 12 mm high.
Pricing: Varies according to LCD size; an SFDL Series driver board designed to backlight an NEC NL 10276BC13-01C 6.5" TFT LCD is less than $20 in production quantities.
Availability: Delivery is typically four weeks ARO.
