8-bit Constant-Current LED Driver with Operating Voltage of 3.3 V
The TB62725 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 8-bit constant-current output, a 8-bit shift register, a 8-bit latch and a gate circuit.
These drivers have been designed using the Bi-CMOS process.
