Need LED backlit LCD 200mA driver with PWM dimming

STM32F746G-disco board currently uses a STLD40D led driver. I am switching to an LCD that had 1000 nit output that can draw 150mA.  Looking for a driver that can handle about 200mA with PWM dimming capability.  

Any suggestions appreciated.

If you want to supply the backlight LED from the 3.3V, STMicroelectronics unfortunately does not currently have a suitable boost converter for the output current of 200mA and an LED voltage of approx. 16V in its portfolio.
