16-bit constant current LED driver with operation supply of 3.3V to 5V

The TB62726AFNA is comprised of constant-current drivers designed for LEDs and LED displays. The output current value can be set using an external resistor. As a result, all outputs will have virtually the same current levels. This driver incorporates a 16-bit constant-current output, a 16-bit shift register, a 16-bit latch and a gate circuit. These drivers have been designed using the Bi-CMOS process.
