Description

  • Typical Application for CAT4004 4-Channel Constant Current LED Driver with EZDim. The CAT4004 provides four matched low dropout current sources to drive LEDs. An external resistor on RSET sets the current in the LED channels. Each LED channel includes an individual control loop allowing the device to handle a wide range of LED forward voltages while still maintaining tight current matching
