Hi Jingguo,
Please also share your design requirement, like inductor current ripple/output current ripple, input voltage range...
or you can share the calculation file, and I can help you review it.

Hi Hailee
Customer is using Nichia’s laser power as attached. VIN=36V, and maximum current is about 3.8A.

Hi Jingguo,
Generally, it's okay.. But for parameters' selection, please provide a detailed design requirement, like inductor current ripple and output current ripple. Or you can refer to our datasheet- 9.2.1 EN PIN PWM Dimming Application for 10 LEDs, it is clear to help you verify it.

Hailee.
