7.4.1 MODE Pin

TPS51386 has a MODE pin that can be used to toggle mode of the device by pulling it high (> 0.8 V) or low (< 0.4 V). When the MODE pin is pulled high, the pin enables the converter to operate in Out-of-Audio (OOA) mode. When the MODE pin is pulled low or float, the converter goes into Power Save Mode (PSM). The MODE pin can be toggled dynamically, even when the converter is in operation.
