Product Summary

The TB62726AFG is a 16-bit Constant-Current LED Driver with Operating Voltage of 3.3-V and 5-V. It 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. The TB62726AFG incorporates 16-bit constant-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 Bi-CMOS process.
