The IS31FL3726 is comprised of constant-current drivers designed for color LEDs. The output current value can be set using an external resistor. The output current value can be adjusted from 5mA to 60mA through the external resistor. As a result, all outputs will have virtually the same current levels. This driver incorporates 16-bit constant t-current outputs, a 16-bit shift register, a 16-bit latch and a 16-bit AND-gate circuit. These drivers have been designed using the CMOS process.
