CAT4104 Overview
The CAT4104 provides four matched low dropout current sinks to drive high−brightness LED strings up to 175 mA per channel. The LED channel current is set by an external resistor connected to the RSET pin. The LED pins are patible with high voltage up to 25 V supporting applications with long strings of LEDs.
