The working principle of the RT9618AGS is based on a synchronous switching buck converter design. The RT9618AGS takes in an input voltage from a battery, DC power supply, or other source, and then Buck converter uses a switching architecture to convert this input voltage to a preset output voltage. This output voltage can be adjusted by varying a resistor at the feedback pin of the IC. The RT9618AGS has a low input voltage range that allows it to be used with battery voltage or lower input voltage, while the adjustable output voltage make it suitable for use in many industrial applications.

The RT9618AGS has a low-side synchronous driver and an on-board Schottky diode. It uses current mode control for a fast transient response and excellent line/load regulation.
