Description
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 supply voltage range.The three LED pins are compatible with high voltage up to 25 V supporting applications with long strings of LEDs.Three independent control inputs PWM1, PWM2, PWM3, control respe
