Texas Instruments TPS25840-Q1 | Demoboard PMP40544
USB-A SDP/CDP charge port converter with STB protection and cable compensation
Overview
| Topology | Buck Converter |
| Input voltage | 6-36 V |
| Output 1 | 5 V / 2.4 A |
| IC revision | E1 |
Description
This reference design is for an automotive USB Type-A charger with 3 meters USB-IF near-end compliant. The TPS25840-Q1 is used as DC-DC regulator and data switch and TUSB217-Q1 is used as high speed signal conditioner to improve signal quality. The efficiency of the solution is 93.3% at a 12-W output, which leads to only 20.5°C temperature rise. Programmable cable droop compensation helps portable devices charge at optimum current and voltage under heavy loads. USB 2.0 high-speed near-end eye compliance test is passed on the design with a cable as long as 3 meters.
Features
- Good eye performance with a cable as long as three meters
- 93.3% efficiency at 12-W output
- Only 20.5°C temperature rise
- Programmable cable droop compensation for optimum charging
Typical applications
- Automotive USB charge / Automotive media hub
