Beschreibung
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.
Eigenschaften
- 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
Typische Anwendungen
- Automotive USB charge / Automotive media hub
