Texas Instruments TPS25750 | Demoboard TIDA-050047
Integrated USB Type-C® power delivery (PD) and charging reference design for 2-4 cell batteries
Overview
| Topology | Buck-Boost Converter |
| Input voltage | 3.6-2.4 V |
| IC revision | A |
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
