CAT4103 Overview
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.
