TPS61081: Rss setting

Part Number:TPS61081

Hi,

We got a question from the customer about TPS61081.
Could you help us?

[Question]
They are considering using TPS61081 for constant current output. They checked the schematics of TMDSSK3358. It uses Rss=44.2k, Rfb=10 and describe Iout=32mA. But they calculated based on this condition, so the result is Iout=22.1mA. Could you check it is ok or not with thier calculation result?

 New Vref = Rss*Iss = 44.2k*5uA = 221mV
 Iout = New Vref / Rfb = 221mV / 10 = 22.1mA

Best Regards,
tateo
