This reference design is an EMI-optimized design for automotive USB Type-A charger with single 12-W output. The TPS25846-Q1 is used as DC-DC regulator and port controller. The switching frequency is 400kHz. 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 design time.
