16-bit Constant-Current LED Driver with Operating Voltage of 3.3 V

The TB62726 series 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.
