This reference design is an EMI-optimized design for automotive USB Type-C® charger with dual 15-W output. The TPS25850-Q1 is used as DC/DC regulator and port controller. The switching frequency is 2.2 MHz. The front-end filter is designed and PCB layout is optimized to pass stringent CISPR 25 Class-5 conducted Electromagnetic Interference (EMI) standards. This reference design has already been tested to CISPR 25 Class-5 conducted EMI standards, which accelerates customer design time.
