Description
This reference design is for an automotive dual-port USB Type-C charger in 30-mm×30-mm dimension. The TPS25833-Q1 is used in each port as DC-DC regulator and port controller. The efficiency of solution is 92.93% at 2×15-W output, which leads to only 55.9°C temperature rise. In an 85°C environment, the highest temperature on the board is 137°C. Programmable cable droop compensation helps portable devices charge at optimum current and voltage under heavy loads.
Features
- Small design size
- 92.93% efficiency at 2x15-W output
- Good thermal performance
- Programmable cable droop compensation for optimal charging
Typical applications
- Automotive USB charge / Automotive media hub
