Minimal output current at LED channel TI LP8862

Other Parts Discussed in Thread: LP8862-Q1

I have a question about TI LP8862-Q1. Is the minimal LED current per channel about 30mA like in picture bellow or we can drop it even lower by incrising the R_iset? We want to set LED current to around 12mA- 17mA, that means that following resistor is about 450- 500 kOhm.

Tell me, if I am in right direction, please.

Best regards, Tomaž

Hi,

We do not recommend setting the current very low. The accuracy may not be very good and is not guaranteed. What is the end equipment that customer is using this device in? Why so low current is needed?
