Per data sheet (p.9) of the LT3517, when the CTRL pin voltage is less than 1V, the LED current is: ILED =VCTRL/(10*RSENSE).
Question: What precision of this equation in temperature range of +10 to +50 Celsius degrees?
Attached is the data gathered on Vctrl vs VISP – VISN Threshold
This was gathered using a DC1279A eval board
Thank you very much Mikee_Lacson_00 !
