CAT4004 4-Channel Constant Current LED Driver with EZDim™
FEATURES
Four LED current sinks with tight matching Low Dropout Driver 130mV at 30mA No switching noise Shutdown current 1μA LED current set by external resistor Dimming via 1-wire EZDimTM interface Thermal shutdown protection RoHS Compliant 8-lead 2mm x 3mm TDFN package
DESCRIPTION
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.
The EN/DIM logic inputs s...
