Other Parts Discussed in Thread: TPS92200
In the following diagram,the green line is the LED-290+ which is the output of the TPS92200.
I send zero voltage to DIM pin of TPS92200.
So the output voltage of TPS92200 start to turn off.
The voltage of LED anode down slowly.
I wonder this voltage will not turn off the LED totally.
LED is still a little on.
How could I turn off the LED instatly (when I send 0 to the DIM pin)?
