CAT4109

3-Channel Constant-Current

RGB LED Driver with

Individual PWM Dimming

Description

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.

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.

disable the LED outputs whenever the die temperature exceeds 150°C.
