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.
