Abstract
A method of operating a Universal Serial Bus Power Delivery (USB-PD) power converter includes responsive to detecting an absence of a load device sending a low power mode signal from a secondary-side controller, coupled to control a secondary-side of the USB-PD power converter, to a primary-side controller coupled to control a primary-side of the USB-PD power converter, and transitioning the secondary-side controller from a secondary-side active mode to a secondary-side low power mode, transitioning the primary-side controller from a primary-side active mode to a primary-side low power mode responsive to receiving the low power mode signal, responsive to detecting a connection of the load device sending an active mode signal from the secondary-side controller to the primary-side controller, and transitioning the secondary-side controller from the secondary-side low power mode to the secondary-side active mode, and transitioning the primary-side controller from the primary-side low power mode to the primary-side active mode.
