Other Parts Discussed in Thread: TPS53119
I am looking for a candidate for switching regulator, that I can power core voltage (0.9V) of Arria 10 FPGA with.
After added necessary parameters (ext sync, etc), Webench recommended LM27403. Although it meets most of
the requirements Altera/Intel specified, seems like load regulation is out of limit.
According to PDN tool of Intel load regulation of 5% is accepted (45mV), however Webench simulation indicates almost
60 mV overshoot during. Due to other design constraints, i need to use 625 kHz switching frequency.
Is it possible to tweak on the load regulation or it would be preferable to use other regulator?
Thank you for your answer in advance.
Best regards,
