Using LMD18201 as LED Driver

Other Parts Discussed in Thread: LMD18201

Hello all.

I am making a light controller so I have used the LMD18201 IC to drive my 50W Led. I am trying to dim it using PWM.

I am deriving PWM from arduino. So i need to know do i need to connect the bootstrap capacitors.?

Another question is at low PWM rather than dimming the Led is blinking. Why is that happening?

And also for 8-bit PWM LED burns bright for any PWM above 70. Why so?
