LED Backlight Driver

Monday, May 03 2010

Endicott Research Group (Endicott, NY) has introduced a new LED driver that can simultaneously and efficiently power up to 8 strings of high brightness LEDs (HBLEDs) and provides a total 50W of power.

The new Smart Force™ SFD2C Series is a full-function LED driver board that features a dual output that provides a total maximum current of 1200 mA - 600 mA per side - for high efficiency power to LED backlights used in LCDs up to 24” diagonal.

Ideal for LED backlights utilizing larger HBLEDs, the SFD2C can power up to 4 strings of HBLEDs per side with a maximum current of 150 mA per string. It features a wide input voltage design (10-20V) and 60V maximum output voltage.

The SFD2C offers onboard and external PWM dimming, with dimming ratios up to 5000:1 achievable, along with separate brightness and enable controls. It measures 2.20” x 5.61” (55.9 x 142.5 mm), and is less than 15 mm high.
