CAT4109 - 3-Channel Constant-Current RGB LED Driver

CAT4109 Description

3-Channel Constant-Current RGB LED Driver with Individual PWM Dimming CAT4109, CAV4109 .
The CAT4109/CAV4109 is a 3. channel constant. current LED driver, requiring no inductor.

CAT4109 Features

* 3 Independent Current Sinks up to 175 mA rated 25 V
* 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

CAT4109 Applications

* with long strings of LEDs. Three independent control inputs PWM1, PWM2, PWM3, control respectively LED1, LED2, LED3 channels. The device also includes an output enable (OE) control pin to disable all three channels independently of the PWMx input states. Thermal shutdown protection is incorporated i
