The CAT4104 is a LED driver with four matched current sinks capable of driving up to 175 mA per channel. All current sinks are programmed by a single resistor from the RSET pin to GND. Enable and dimming control is available via the EN/PWM pin. The evaluation board contains one CAT4104 in a typical application circuit. Four test points labeled T4 through T7 are available to connect the cathode side of an LED string to the CAT4104. Trimmer potentiometer R2 can be adjusted to change the LED current. The RSET pin of the CAT4104 is a fixed 1.2 V reference and the LED current is set by changing the current through the RSET resistor (R1 + R2). The CAT4104 has a typical dropout voltage of 400 mV for 175 mA LED current.
