The TL4242 is characterized for operation from 40C to 150C. An external shunt resistor in the ground path of the connected LEDs is used to sense the LED current. A regulation loop holds the voltage drop at the shunt resistor at a constant level of 177 mV (typical). The constant-current level can be adjusted by selecting the shunt resistance, RREF. Calculate the typical output current using the equation: |
