LED Driver Powers Multiple Strings of High Brightness LEDS
Endicott Research Group (ERG) announces a new LED driver that can simultaneously and efficiently power up to 8 strings of high brightness LEDs (HBLEDs). The 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. Well suited 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 to 20V), 60V maximum output voltage, and provides a total 50W of power (25W per side). 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.
