FPGA power supply is necessary, what is the difference between this thousand yuan power supply solution

Field Programmable Gate Arrays (FPGAs) are typically thousands of programmable logic cells. A matrix of wires and programmable switches interconnects the individual logic cells. A typical design includes simple logic specifying each cell. function and selectively close switches in the interconnect matrix.

FPGAs face power challenges

Field Programmable Gate Arrays (FPGAs) are typically thousands of programmable logic cells. A matrix of wires and programmable switches interconnects the individual logic cells. A typical design includes simple logic specifying each cell. function and selectively close switches in the interconnect matrix.

Designing a power system for an FPGA is no easy task. FPGAs are highly configurable semiconductor devices that are used in a wide variety of applications and end markets. Common examples include communications, automotive, industrial, medical, video, and defense applications. Due to their high configurability, different components can be placed around them to form the final system design. While there may be countless applications and systems, a common characteristic of all designs is that they all require power.

With the rapid popularization of high-performance FPGAs and ASICs, power module design also faces certain challenges – applications require wider wireless network bandwidth to drive, while data centers require higher power density, faster load transients dynamic response and more efficient work efficiency.

How to deal with different power supply needs
