Automotive dual port USB Type-C reference design (2x 15 W)


Design files


This reference design showcases a system implementation of a dual port USB Type-C charger. The design includes input reverse polarity protection, input filtering and two individual USB Type-C charger circuits, which can supply up to 3.0 A each. The circuit has been space optimized to fit into a PCB area of 38 mm x 41 mm (without connectors) to meet current automotive requirements. Very good efficiency ensures that the maximum temperature rise is only 45.5 K.

  • High efficiency for low power dissipation in space constrained applications
  • Small form factor to fit into space constraint applications
  • Uses smart diode controller for reverse polarity protection
  • Includes an input filter to minimize the reflected ripple at the input of the two converters
  • Incorporates output voltage droop compensation
