Dimming function-2 ADD5203

Dear Sir/Madam,

 

Our customer is studying with your ADD5203 as LED torch.

So LEDs will be coming on continuously.

And need the dimming function as linear current up and down.

 

Your datasheet shows 2.9A max current.

And also showed  "LED current adjustable up to 30 mA for each channel" on page-11.

 

Does this mean the dimming function 2.87A to 2.93A (2.9A +/-30mA) when we put the resister on Rset correct?

Otherwise can we adjust the dimming 0A to 2.9A by 30mA steps??

 

Thanks Kaos
