True Load Disconnect During Shutdown

When the input voltage is below the UVLO threshold or the EN pin is pulled low, The TPS61376 is in shutdown mode and all the functions are disabled. The TPS61376 integrates a load disconnect function where the ISO FET between the VP and SW pin will completely cut off the path between input and output when the device is disabled, so the output voltage can remain at 0 V.

#GUID-5FEA634D-F01C-424B-8C42-AA23DE0F09CC shows the process of shutdown when the device gets disabled.
