| IC revision | A |
Description
This user’s guide describes the TPS25741 and TPS25741A evaluation module (TPS25741EVM-802 andTPS25741AEVM-802). The TPS25741EVM-802 and TPS25741AEVM-802 contain evaluation andreference circuitry for the TPS25741 and TPS25741A, which are dedicated USB Type-C™ power delivery(PD) source controllers. The TPS25741 and TPS25741A devices support multiplexing of two existing inputvoltage rails onto VBUS. This feature is uniquely suitable for desktop applications where 5 V and 12 V (or5 V and 9 V) already exist. These EVMs are designed to highlight the mux feature, by using 2 Buckconverters to create 5 V and 12 V (or 5 V and 9 V) and then multiplex between them. The EVMs are alsodesigned to support port power management (PPM) for dual-port applications, by connecting two EVMstogether. In addition, this EVM supports BC1.2 charging using the TPS2514A connected to the DP andDM line.This EVM features a barrel jack input with reverse voltage protection to allow for easy demonstration usinga 24-V, 60-W output adapter
Features
TPS25741 Built in IEC 61000-4-2 ESD Protection on CC1 and CC2 pinsState-machine implementation requires no firmwareVariable output voltage of 5V, 12V, and 20V depending on requestUp to 5A output current with captive cable attached. Default is 3ASmooth transitions between 5V, 12V, and 20V that are compatible with USB PD specification
Typical applications
- Desktop, Monitor, PC Docking, USB power delivery adaptors with data
