    Abstract: A USB Type-C/Power Delivery controller chip includes a first pin for receiving a first voltage, a second pin for receiving a second voltage, and a third pin for coupling to the CC pin of a USB connector. The USB controller chip includes a VCONN power supply circuit having a blocking field effect transistor (BFET) coupled in series with a hot-swap field FET (HSFET) between the first and third pins, and first and second Zener diodes coupled anode-to-anode between the HSFET's source and gate. A cable detection circuit includes a BFET coupled between the second and third pins, and a Zener diode coupled between the BFET's gate and a lower rail. A power delivery physical layer circuit includes a receiver and a transmitter, each coupled to the third pin through a respective BFET, the respective BFETs each having a Zener diode coupled between respective gates and the lower rail.

    Abstract: A power controller that includes first and second buck controllers and a power balancer. The first buck controller is configured to receive a first power rail at a first voltage and generate a first output signal. The second buck controller is configured to receive a second power rail at a second voltage and generate a second output signal. The power balancer is configured to receive an average current for the output signals and generate, based on the average current, a reference voltage to be received by the second buck controller. The output signals are combined to create a output power rail such that the first buck controller functions as a voltage source for the output power rail and the second buck controller controls, based on the reference voltage, an amount of current in the output power rail received from each of the buck controllers.
