This reference design is a small size design (40 mm × 40 mm) for automotive USB Type-C® charger with dual 15-W output. The TPS25850-Q1 is used as DC/DC regulator and port controller, The efficiency of solution is 92.37% at dual 15-W output. Programmable cable droop compensation helps portable devices charge at optimum current and voltage under heavy loads. And a negative temperature coefficient (NTC) thermistor is implemented for intelligent thermal management to reprogram the output voltage in over-temperature condition.
