Hello, Please ask a question about BCR402UW6_18 Datasheet

# Example questions: ➢ How does the pwm method shown in figure 3c improve the switching performance and resolution of the led driver?
➢ What are the three primary benefits of using the bcr40x led driver compared to more complex switching regulator solutions?
➢ Explain how the internal resistor (r int) of the bcr401/2/5 series functions and how an external resistor (r ext) can be used to modify the led current.
