We are working on DALI LED control gear type product. We are using TPS92515 as LED driver and its controlled through Iadj pin (analog dimming). Our issue is even if we give input zero (GND) to control pin (Iadj), there is 3mA current through LED and it is ON, but at low brightness. This means we cannot turn OFF the led by issuing DALI command DAPC 0 (OFF command), but DALI spec says LED shall switch off upon OFF command (Refer. Sec. 11.3.2, page 54, IEC62386-207:2016). Will this be an issue with DALI compliance certification? Any help would be appreciated.
Thanks
