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.
