To boldly go to 3A 100W, follow the bouncing ball
While USB Type-C opens up opportunities for high power delivery to charge phones, tablets, and laptops, there are plenty of larger electronic devices that can also benefit. FTDI Chip took the opportunity at electronica to demo how their FT4233H bridge IC can support applications up to 100W with 3A current delivery, charging anything with a USB connector from a notebook to digital signage.
The standard USB set up included a laptop with a Type-C connector to the FT4233H chip. A configurable port acts as a power sink or source while the other port is solely a power sink charging support in which a power brick is plugged into. Power and data coming out cause the ball to bounce. Flipping the switch on the power supply enables the charging port which allows for the renegotiation with the laptop as to what is going to supply the current and without interruption of the data transfer — so the bouncing ball continues to bounce.
