SLVSD02E March 2015 – August 2021 TPS65982
The TPS65982 controls three separate power paths making it a flexible option for Type C PD charger applications. In addition, the TPS65982 supports VCONN power for e-marked cables which are required for applications which require greater than 3 A of current on VBUS. Figure 10-1 below shows the high level block diagram of a Type C PD charger that is capable of supporting 5 V at 3 A, 12 V at 3 A, and 20 V at 5 A. The 5 V and 12 V outputs are supported by the TPS65982 internal FETs and the 20-V output uses the external FET path controlled by the TPS65982 NFET drive. This Type-C PD charger uses a receptacle for flexibility on cable choice.
