CAT4103 3-Channel Constant-Current RGB LED Driver Description The CAT4103 is a 3−channel, linear based constant−current LED driver designed for RGB LED control, requiring no inductor and provides a low noise operation. 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. A high−speed 4−wire 25 MHz serial interface controls each individual channel using a shift register and latch configuration.
