The USB-C interface is revolutionizing the way we charge our electronics devices. In addition to data transfer, USB-C supports bidirectional power flow at a much higher voltage range than traditional USB terminals. However, the current system architecture for dual or multiple USB Type-C ports is complex and faces challenges. This white paper:

  • Proposes a new system architecture using a buck-boost voltage regulator and a combo battery charger
  • Discusses how this architecture simplifies design and fully supports all USB-C functions
  • Describes how to apply this architecture to the adapter side to implement a programmable power supply
