Description

This reference design is an EMI-optimized design for an automotive dual USB Type-C® power delivery (PD) charger with 60 W per port. The TPS25772-Q1 device is used as a dual USB Type-C PD controller with a buck-boost regulator. The TPS55288-Q1 device is used as a buck-boost regulator for another port. The maximum efficiency of this reference design is 96.45%. The input EMI filter is designed and PCB layout are optimized to pass the stringent CISPR 25 Class 5 conducted Electromagnetic Interface (EMI) standards. This reference design was tested to be compliant with the CISPR 25 Class 5 conducted Electromagnetic Interface (EMI) standard.
