USB Bus Power Source

USB Bus Power Source is from PCIe 12V ( 12V Step-Down to 5V)

Note: Synchronous step-down regulator

  • High Frequency, Synchronous, Rectified, Step-Down, Switch-Mode Converter
  • Operates at High Efficiency Over a Wide Output-Current-Load Range
  • Non-Latch OCP, OVP, and Thermal Shutdown

USB Port Current-limited Power Switch 2.0A (70mΩ on-resistance) Single Channel Current-limited Power Switch (UL File Number E322375)
The devices have fast short-circuit response time for improved overall system robustness, and have integrated output discharge function to ensure completely controlled discharging of the output voltage capacitor. They provide a complete protection solution for applications subject to heavy capacitive loads and the prospect of short circuit, and offer reverse current blocking, over-current, over-temperature and short-circuit protection, as well as controlled rise time and under-voltage lockout functionality.
Computer Platform Requirements Desktop computer equipped with a PCIe 2.0/3.0 x4, x8, x16 slot
Computer Platform
    • Computer with PCI Express slot (x4, x8, x16)

Note:
For the best performance (5.0 Gbps), It should be installed in a PCIe Gen 2 compliant slot in the host computer.  Most computers have PCIe Gen 2 (5.0 Gbps) throughput on x8 or x16 slots.
A PCIe Gen 1 compliant slot reaches up to 2.5 Gbps throughput

Operating System Requirements
  • If OS is Windows 8 or later , there are inbox driver for Renesas USB 3.0 Host Controller. OS will detect the presence of new hardware and then install Renesas USB 3.0 Host Controller driver automatically.
