US 2020/0403426 A1 · ADAPTER POWER ADD-UP FEATURE FOR MULTIPORT SYSTEMS

Abstract

One or more embodiments are directed to a multiport power delivery architecture that reduces the cost and maximizes the power utilization. According to some aspects, an adapter power add-up feature of the embodiments can combine the power of two or more adapters. The total power can be used to support CPU Turbo events and Quick Charge function. In one aspect, one charger operates as voltage source or current source and the other(s) as current source(s). When the system demand is high enough for all chargers may operate as current sources, the battery will supply the rest of the system demand. The proposed implementation of adapter power add-up feature can enable simple control scheme. Customers can set up BGATE control priorities to determine which charger to handle the BGATE control.
