LED Driver, Constant Current Programmable with 32 Dimming Levels

The CAT4003B and CAT4004B provide respectively three and four matched low dropout current sources to drive LEDs. The CAT400XB requires no external RSET resistor. The LED current is internally set to 25 mA when the device is first enabled. Each LED channel includes an individual control loop allowing ? Low Dropout Driver 75 mV at 20 mA\n? Can drive LEDs at lower VIN\n? Dimming via 1-wire EZDimTM Interface\n? higher resolution dimming\n? 3, 4 LED Current Sinks with Tight Matching\n? 32 Dimming Levels\n? No Switching Noise\n? Shutdown Current less than 1 μA\n? 25 mA Max LED Current per Channel\n? ;
