CAT4109 Datasheet (ON Semiconductor) - 3-Channel Constant-Current RGB LED Driver

CAT4109, 3-Channel Constant-Current RGB LED Driver

The CAT4109/CAV4109 is a 3 *channel constant *current LED driver, requiring no inductor.

LED channel currents up to 175 mA are programmed independently via separate external resistors.

Low output voltage operation of 0.4 V at 175 mA allows for more power efficient designs across wider

* LED Current Set by External Low Power Control Resistors

* Individual PWM Control per Channel

* Low Dropout Current Source (0.4 V at 175 mA)

* Output Enable Input for Dimming

* “Zero” Current Shutd
