8­bit Constant­Current LED Driver of the 3.3­V and 5­V Power Supply Voltage Operation
The TB62725BPG/BFG/BFNG are comprised of
constant­current 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 an 8­bit constant­current output, an
8­bit shift register, an 8­bit latch circuit and an 8­bit AND­gate
circuit.
These drivers have been designed using the Bi­CMOS process.
This devices are a product for the Pb free.
