16-bit Constant-Current LED Driver with Operating Voltage of 3.3-V and 5-V

The TB62726A series are 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 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.

The suffix (G) appended to the part number represents a Lead(Pb)-Free product.
