Tool/software:
Hi Team,
I have a design challenge due to the provision in the product design to allow users to change LED brightness.
Below is the IR led VI characteristic, user will be able to change Led forward current(If) from 40mA to 400mA, With Vin=5V, which LED driver would you recommend?
| If | Total Vf |
| 40mA | 3.6V |
| 80mA | 4.06V |
| 100mA | 4.3V |
| 120mA | 4.58V |
| 140mA | 4.8V |
| 160mA | 5.0V |
| 180mA | 5.2V |
| 200mA | 5.4V |
| 300mA | 5.8V |
| 400mA | 6.0V |
Regards,
James
