TPS61165: TPS61165 Output voltage set

Part Number: TPS61165

Tool/software:

Hello,

TPS61165DRVRG4 is constant current LED driver. The LCD module backlight has a spec for both voltage and current. for example, our backlight has a current spec 180mA and voltage spec typ 9.6V, max10.2V.

In TPS61165 design, the current can be set by select R(set) = 200mV/180mA= 1.11 ohm. However, how can we assure the TPS61165 output voltage will < 10.2V.

Any option to set fix output voltage?

or share Which IC is well suited as per attached photo.

I have attached the Backlight circuit diagram.
