10 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

10.1 Application Information

The typical applications of the TPS65982 include chargers, notebooks, tablets, ultrabooks, docking systems,

dongles, and any other product supporting USB Type-C, USB-PD as a power source, power sink, data DFP, data

UFP, or dual-role port (DRP), or supporting both USB Type-C andUSB-PD. The typical applications outlined in

the following sections detail a Fully-Featured USB Type-C and PD Charger Application and a Dual-Port

Notebook Application Supporting USB PD Charging and DisplayPort.

10.2 Typical Applications

10.2.1 Fully-Featured USB Type-C and PD Charger Application

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 77 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.

10.2.1.1 Design Requirements

For a USB Type-C and PD Charger application, Table 11 lists the input voltage requirements and expected

current capabilities.
