Working Principle

The LM5009AMMX/NOPB is a synchronous buck switching regulator. This type of regulator is also known as a step-down regulator, because it uses an inductor to store energy and then step down the input voltage to a desired output voltage. The voltage step-down is accomplished by using a electronic switch that turns on and off rapidly, allowing energy to be transferred to the output as a pulse-width modulated (PWM) signal. The on and off times of the switch determine the output voltage.
