12 V and 24 V powered USB sockets, on an NCR cash register. PoweredUSB, also known as Retail USB, USB PlusPower, USB +Power, and USB Power Plus, [1] is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter.
The USB Power Delivery specification revision 2.0 (USB PD Rev. 2.0) has been released as part of the USB 3.1 suite. [ 58 ] [ 65 ] [ 66 ] It covers the USB-C cable and connector with a separate configuration channel, which now hosts a DC coupled low-frequency BMC -coded data channel that reduces the possibilities for RF interference .

One USB 1.1 (LS & FS) controller and PHY, host and device support, 1.5 Mbps (Low Speed) and 12 Mbps (Full Speed) Two UART controllers; Two SPI controllers; One QSPI (quad SPI) controller (SSI), supports 1 / 2 / 4-bit SPI transfers, 1 chip select; Two I²C controllers; Eight PIO (programmable input–output) state machines; 16 PWM channels
The removal tool engages with the front portion of the contact and pushes it through to the back of the connector. Rear release contacts are released and removed from the rear (wire side) of the connector. The removal tool releases the contacts from the rear and pulls the contact out of the retainer.
Modern high-powered graphics processing units do the same thing, resulting in most of the power requirement of a modern personal computer being on the +12 V rail. When high-powered GPUs were first introduced, typical ATX power supplies were "5 V-heavy", and could only supply 50–60% of their output in the form of 12 V power.
Since the input is MOS technology, there is very little current flow, allowing for very low power control signals. The device is constructed with two MOSFET inputs and a pair of BJT output stages. Input MOSFETs are configured to allow turn on control during positive and negative half cycles.
Additional to the traditional screw contacts the electrical connection between the module and other parts of the power electronic system can also be achieved by pin contacts (soldered onto a PCB), press-fit contacts pressed into PCB vias, spring contacts that inherently press on contact areas of a PCB or by pure pressure contact where corrosion-proof surface areas are directly pressed together ...
Under the USB 3.2 specification, released 22 September 2017, [11] existing SuperSpeed certified USB-C 3.1 Gen 1 cables will be able to operate at 10 Gbit/s (up from 5 Gbit/s), and SuperSpeed+ certified USB-C 3.1 Gen 2 cables will be able to operate at 20 Gbit/s (up from 10 Gbit/s). The increase in bandwidth is a result of multi-lane operation ...
