TPS92511: Suggestion on constant current buck converter

Part Number: TPS92511

Hi TI Team,

We need a constant current of 500 mA for a string of LEDs with dimming functionality for a 7inch TFT LCD.

Nominal input voltage is 12V.

LED forward voltage is in the range of  8.7 V to 10.5 V.

Please suggest a suitable IC for the same.

Regards
