Multiport power sharing allows multiple electronic devices to be charged or powered simultaneously. These adapters typically have multiple output ports, each capable of delivering power to different devices including smartphones, tablets, laptops, or other USB-powered consumer electronics, smart home, IT, and industrial equipment products. The power sharing feature of the SZPL3002A buck converter IC is designed to efficiently distribute power among multiple devices connected to the charger or adapter. As an example, for a 65W multiport adapter, when a single device is plugged in, the PD Controller communicates with the device to determine its power requirements and if the device has a low battery level of 20%, it will receive 100% of the available power.
