During shutdown, when connected to a power supply, a path from the power supply to the positive output conducts through the inductor and an external diode. Optionally, to fully disconnect the positive output VPOS during shutdown, add an external PMOS (Q1). The BSW pin controls the gate of the PMOS. When choosing a proper PMOS, the VGS and VGD voltage ratings must cover the input voltage range, the drain current rating must not be lower than the maximum input current flowing into the application, and conditions of the PMOS operating area must fit.
If there is no intention to use an external PMOS, leave the BSW pin floating.
