Ideally the LED output current is proportional to the duty cycle of the PWM frequency at the input pin DIM.
In reality, however, this depends on several factors which are described in the datasheet of LED2001: frequency, selected inductor and output capacitor, layout.

Thanks Peter , our customer bought LED2001 EVB to test DIM performance then will see the relationship between the frequency and duty cycle.
Best regards,
