Texas Instruments TPS25750 | Demoboard TIDA-050047

Integrated USB Type-C® power delivery (PD) and charging reference design for 2-4 cell batteries

Overview

TopologyBuck-Boost Converter
Input voltage3.6-2.4 V
IC revisionA

Description

This reference design features charging up to 20 V at 5 A without the need for any external FETs, enabling a much smaller solution size and reducing total BOM cost. A microprocessor is also not necessary as the TPS25750 power delivery (PD) controller will handle the I2C communication to the BQ25792 battery charger IC. This I2C capability and the TPS25750 web-based GUI greatly simplify the firmware development process.

Features

  • Easily evaluate the combination of a high-efficiency 5-A switch-mode buck-boost charger and USB Type-C and PD Controller with integrated switches.
  • Use of Aardvark™ connector to change the PD controller flash settings to meet the user's desired configuration.
  • Use of onboard internal I2C lines between PD controller and battery charger to program the battery charger without need for anything other than a one time flash
  • Small solution size to highlight the compact design using both of the chosen integrated circuits.

Typical applications

  • power banks
  • Power tools, retail automation and payment, industrial applications
  • Wireless speakers, headphones, Other personal electronics, Other personal electronics and industrial applications
