TLC59116 power dissipation

Other Parts Discussed in Thread: TLC59116

In my design I have three green leds (forward voltage each ~3.5V) in serial per channel and a ledvoltage of 12V. I want to minimize the power dissipation across the driver ic. I'm looking for informations about the optimal driver voltage drops.

Hello Matthias,

When you check Figure 9 in the datasheet of TLC59116, you can see the minimum voltage to get a specific current. When you have a LED voltage 1V higher than the forward voltage of your diode chain, you are for sure on the save side.

Best regards,
Brigitte
