Function and benefit PCIe based USB power booster that extracts the USB signals from the USB chip and converts 3.3V to 5V at up to 1A to power a USB device. Enables a USB device to operate by supplying a dedicated 5V power rail from the PCIe interface. Compatibility and interfaces Designed for PCIe interfaces only; other interfaces are not supported. The PCIe standard used on laptops provides USB 2.0 signals and a 3.3V power supply for this module to operate. How it works The device processes USB signals from the computer and boosts the supply from 3.3V to 5V/1A to power connected USB devices. Important caveats Because USB signals are output by the computer, some computer displays may not output the signals correctly or may output no signals at all, which can cause the card to be unusable. This is not a defect of the card. If the internal USB bridge is damaged, the card cannot be used. Performance and power details Output voltage and current: 5V at up to 1A to supply USB devices. The description specifies 3.3V input from the PCIe side and 5V/1A output for USB devices. Use scenarios and applications Use Case 1: Power USB peripherals that require a reliable 5V supply from a PCIebased system. Use Case 2: Situations where the USB power available on the host is insufficient and a dedicated 5V supply is needed via the PCIe interface. Use Case 3: Deploying USB devices on systems where PCIe provides USB signals but the device needs a separate 5V/1A power source.
