I am planning to use ADP8140 ELD controller to drive backlight LED module with operating voltage of 26V - 29V with max 50mA current. How do I estimate the current sink headroom voltage range for 50mA? In datasheet specs, I couldn't find the specs for 50mA current. Please let me know.
Also, I am planning to use PWM dimming method, in that case out of two available options which will be better - ADP8140ACPZ-1-R7 or, ADP8140ACPZ-2-R7?
If I use only one SINK pin, can we still detect FAULT condition?
Thanks & Regards,
