Risk Mitigation for Powering Low Voltage Processors & FPGAs Directly from Intermediate Bus Voltage

: Traditional overvoltage protection schemes involving a fuse are not suitable for protecting modern FPGAs, ASICs and microprocessors, particularly when the upstream voltage rail is 24V or 28V nominal. A new solution has been created, combining a 38V-rated, 10A DC/DC switching regulator with circuitry to defend against many faults, including output overvoltage. Power and protection for today's most advanced digital logic devices are now available in one compact device.
