Abstract: A power supply architecture for USB Type-C controllers is described herein. In an example embodiment, an integrated circuit (IC) controller comprises a power rail, a VDDD terminal, a VCONN terminal, and a VBUS terminal. The VDDD terminal, the VCONN terminal, and the VBUS terminal are coupled to the power rail, where a VCONN switch is coupled between the VCONN terminal and the power rail, and a VBUS regulator is coupled between the VBUS terminal and the power rail. The power rail is coupled to internal circuits of the IC controller and is configured to provide operating power to the internal circuits from any one of the VCONN terminal and the VBUS terminal.

Abstract: A Universal Serial Bus (USB) Type-C connector subsystem is described herein. An integrated circuit (IC) chip device includes a Universal Serial Bus (USB) Type-C subsystem. The USB Type-C subsystem is to operate an Ra termination circuit that consumes no more than a first predetermined amount of current after the Ra termination circuit is applied to a Vconn line of the Type-C subsystem, or to operate a standby reference circuit in a low power mode of the device to perform detection on a Configuration Channel (CC) line of the Type-C subsystem, where the device consumes no more than a second predetermined amount of current in the low power mode.

Abstract: Example apparatus, systems, and methods receive, by a current digital-to-analog converter (DAC) of a shunt regulator, a first digital code indicative of a first programmable power supply command specifying a first programmable output voltage (Vbus) to be delivered to a voltage bus of a USB-compatible device. The programmable power supply command is compatible with a universal serial bus—power delivery (USB-PD) standard. Responsive to receipt of the first digital code, adjust, by the current DAC, a sink current delivered to a feedback node to adjust an output voltage to the first Vbus for dynamic programmability. The feedback node is coupled to a first input of an amplifier of the shunt regulator and the first Vbus is programmable.

Abstract: A device and method that includes a shunt regulator of a universal serial bus (USB) compatible power supply device is disclosed. The shunt regulator includes an amplifier with an output, a first input, and a second input. The shunt regulator also includes a current digital-to-analog converter (DAC) that is coupled to the first input of the amplifier and a voltage bus node. The current DAC adjusts a sink or a source current delivered at the first input of the amplifier to regulate a programmable output voltage (Vbus) in the USB-compatible power supply device. The current delivered by the DAC is responsive to receipt of a digital code indicative of a programmable power supply command specifying the Vbus to be delivered by the USB-compatible power supply device on the voltage bus node.
