Frequently Asked Questions
What voltages must I consider when designing a power supply for an FPGA?
You must address multiple rails, including the CORE voltage, IO voltage, and auxiliary rails (AUX) which may power internal clocks or phase-lock loops.
How can I optimize the transient response for my FPGA system?
To optimize the transient response, ensure that inductor current reaches the correct operating level, and manage the load switching frequency to prevent ringing.
What is the function of an auxiliary (AUX) rail in FPGAs?
The AUX rail can power internal clocks, phase-lock loops, or transceivers, but due to noise concerns, its voltage ripple must be minimized.
