The LM3423Q1MHX/NOPB works on the principle of Pulse Width Modulation (PWM). This is a technique of controlling a DC motor, servo motor, stepper motor, and other control systems such as LED drivers by varying the width of the pulses. The PWM signal is generated by the PWM controller and is used to control the LED driver.

The PWM signal is fed to the LED driver, which then converts it into an analog signal by comparing it with the output voltage of the LED driver and then switching the power transistor to the desired level. This in turn drives the two LEDs which are connected in series. The LEDs are then modulated in brightness according to the changing width of the PWM signal.

The LM3423Q1MHX/NOPB is a high efficiency and high power LED driver and can be used in a variety of applications. It is particularly well-suited for automotive and industrial applications due to its wide input voltage range, internal power transistor and adjustable output current. It is also able to switch between boost and buck-boost modes and has a wide range of protection features.
