This reference design is a 90W automotive charger for dual USB Type-C® and USB power delivery (PD) with 60W maximum power per port. The TPS25772-Q1 is used as a dual USB Type-C PD controller with a buck-boost regulator. The TPS55289-Q1 is used as a buck-boost regulator for another port. The design uses the TUSB4020BI-Q1 two-port USB 2.0 hub which provides USB high-speed and full-speed connections. The board maximum efficiency is 96.1%. The board is compliant with the stringent CISPR 25 Class 5 conducted and radiated electromagnetic interference (EMI).
