Other Parts Discussed in Thread: TPS61193

I want to select a LED driver for 30 LEDs and every LED with a 5mA current. I want to supply a 24vDC as input power. I want to groups those as 3 rows. And use TPS61193 to drive those 3 rows.

I am reading the datasheet of TPS61193, and I find their is some error information at page 14.

My question is if I can drive my LED use TPS61193. Or BTW, the voltage of the LED is about 2.5~2.8 .

Thanks. If the equation is wrong. I mean I_LED is actually I_OUT?
