CAT4109 driver equivalent, 3-channel constant-current rgb led driver.
* 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.
with long strings of LEDs.
Three independent control inputs PWM1, PWM2, PWM3, control respectively LED1, LED2, LED3 chan.
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 pow.
