Description

This reference design is for an automotive USB Type-C and USB Type-A charger in 45-mm×45-mm dimension. The TPS25833-Q1 is used in each port as DC-DC regulator and port controller. The efficiency of the solution is 93.2% at 27-W output: which leads to only 40.8 °C temperature rise. In an 85 °C environment: the highest temperature on the board is 126.4 °C. Programmable cable droop compensation helps portable devices charge at optimum current and voltage under heavy loads. A negative temperature coefficient (NTC) thermistor is implemented for intelligent thermal management to reprogram the output current limit.
