Constant Current LED Drivers

ec74od806aAustria Microsystems has introduced its AS1110 16-channel constant current LED driver with advanced error diagnostics for open and shorted LEDs. The device uses the serial data input/output lines for the error information read-back so that no additional PCB tracks are needed for LED error diagnostics. It features 16 regulated ports that provide constant current for driving LEDs within a range of forward voltage variations. The output ports are guaranteed to endure a maximum voltage of 15V. Through an external resistor, the currents can be adjusted from 0.5 mA to 100 mA for flexibility in controlling LED brightness. With an accuracy of +/- 3 percent between channels, the driver improves picture quality of LED displays because intensity variations between LEDs and LED modules completely disappear.
