This reference design is the USB Type-C® power delivery for personal electronics or automotive applications, where a USB power delivery (USB PD) supported buck-boost converter is used to generate a wide range output voltage. The TPS55288 is a synchronous buck-boost converter used to convert 12-V auto-battery voltage or 19-V adaptor voltage into USB-PD power supply rails. The TPS65987DH is a stand-alone USB Type-C and PD controller with integrated power path, which can automatically set the output of TPS55288 through an I2C interface based on the PD negotiation results. The output specifications are designed to be 5-V to 20-V, 5-A maximum continuous current under 19-V adaptor input and 3-A maximum continuous current under 12-V battery input for considering efficiency and thermal.
