This reference design is an integrated USB Type-C and USB power delivery (PD) charger for 10 to 12 cell batteries for applications such as e-bikes, high-capacity power banks, and portable power station applications. The design incorporates USB PD3.1 controllers TPS26750 and TPD4S480, a 48V extended power range (ERP) USB port protector together with BQ25756, a four-switch buck boost controller to fully achieve USB PD3.1 function with 240W power capability. The PD controller works with the battery charger controller BQ25756 through I2C communication. BQ25756 supports a wide-range input with four-switch buck-boost configuration, and supports seamless transition from buck, boost, and buck-boost operation mode to provide a highly-efficient, highly-accurate, and reliable charger design. TPD4S480 provides 48V short-to-VBUS, over-voltage, and electrostatic discharge (ESD) protection that allow reliable and safe operation. The design achieved 97.6% full load efficiency.
