How to Calculate Output for Buck Regulator

Hi Guys,

 

Can anyone helo me with calculating the output voltage of this LED Driver - it's an A6211. I'm going to use it to drive a series of Leds that require constant current of 200mA, and a Voltage range of 38.4-43.2V. Accdg to the data sheet you can calculate the current with iLED = Vcsreg /Rsense, that part is ok, but I was unable to calculate for the Output Voltage. Accdg to the datasheet the Vmin depends on Minimum (T-on) and the switching frequency. But I'm having problems with that, can anyone look at the datasheet i attached and see if missed anything?

 

thanks!
