DEI1090-MES-G

LED Driver

DEI1090 device is a 16 pin bipolar integrated circuit designed to drive eight LEDs and provide Pulse Width Modulated (PWM) dimming control according to the luminance curve of incandescent lamps. All eight LEDx pins are driven with an average current proportional to the square of the input dimming vo; ? Emulates incandescent lamp ‘Square Law’ luminance curve.\n? LED dimming controlled by Pulse Width Modulation ranging from 50HZ to 200HZ.\n? Maximum LED current adjustable from 10mA to 20mA.\n? 200:1 Dimming Range at 50Hz. 40:1 Dimming Range at 200Hz\n? Drives 8 LED outputs with matched current dri;
