Intersil: Understanding USB-C Buck-Boost Battery Charging

April 12, 2016 // By Intersil

The USB-C port is a true all-in-one port capable of delivering bi-directional data and up to 100W of power. However, adopting USB-C charging requires a fundamental change to the existing power delivery architecture and presents a new challenge to system designers. This white paper examines how the traditional PC power architecture will change with the adoption of USB-C power delivery, explores different battery charging approaches and explains how a USB-C buck-boost charging topology can provide the flexibility, high efficiency and small solution size designers require.
