This reference design is a small-size and thermal optimization design for automotive USB Type-C®charger with dual 15-W output. The TPS25858-Q1 device is a cost-competitive DC/DC regulator and dual USB Type-C® port controller. The efficiency is 92.83% at dual 15-W output. 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 voltage in overtemperature condition.
