Application report from Texas Instruments on load switches to simplify power supply design. Link here (PDF)

Integrated load switches are electronic relays that can be used to turn on and turn off power supply rails in systems. Load switches offer many other benefits to the system and can include protection features that are often difficult to implement with discrete components. There are many different applications where load switches can be used including, but not limited to:

-Power Distribution
-Power Sequencing and Power State Transition
-Reduced Leakage Current in Standby Mode
-Inrush Current Control
-Controlled Power down

This application note will provide the fundamental basics of what load switches are, when they should be used, and how they can be implemented in a system.
