16-Output Constant Current LED Driver (Output switching high-speed version)
TC62D749 series are an LED driver with a sink type constant
It is the best for lighting the LED module and the LED display.
This IC consists of a constant current output circuit of 16
outputs, a shift register of 16 bits, a latch of 16 bits, and 16 AND
The output current of 16 outputs can be set by one external
Moreover, high-speed data transfer is possible by adoption of a
This IC can operate with the power supply voltage of a 3.3 V
system and a 5 V system.

When the LED driver of high-speed output switching is used, back EMF may occur at the time of output OFF, and
output terminal voltage may rise. Please be careful. It is necessary to reduce inductance to prevent the back EMF. It
is possible to reduce inductance of a substrate by making the power supply for LED wiring shorter and wider
designing the layout pattern.
