Abstract

In an embodiment, a method for providing power to a load using a wireless power receiver includes: wirelessly receiving power using an LC tank; rectifying a voltage of the LC tank using a rectifier; setting a switched-mode power supply coupled between the rectifier and the load in bypass mode; after setting the switched-mode power supply in bypass mode, providing power to the load without switching transistors of the switched-mode power supply; and when wireless power reception is interrupted, providing power to the load by switching one or more transistors of the switched-mode power supply.
