Time delay in the LED current leading edge
The dimming performance of the circuit depends on the input voltage and number n of the
LED composing the row. The higher the voltage applied on the inductor (VIN-n*VLED_FW)
the higher the rising time of the LED current given the inductor value.
The minimum dimming duty cycle is determined based on the specification of the rising /
falling time of the LED current referred to the dimming time and on the dimming frequency.
