Part Number: LM5123-Q1 Other Parts Discussed in Thread: PMP9595 Hi team,
My customer want to design audio amp power for their speaker. We found PMP9595 is pretty match to our requirements. I want to know if we can fulfill the similar power rating…

Hi Vinod,
Thanks for using the e2e forum. I see no restrictions from controller side that would not allow a switching frequency of 500kHz.
If webench does not seem to give you the desired design parameters, I would recommend to use our quickstart…
Hi Gareth,
Please take a look at this reference design:

Hello,
Thanks for your feedback. The LM5122 could probably be the best fit for this application, also because it has a multi phase capability and this might solve the issues related to the overheat of some components. Would you consider the LM5122 in…
Hi SHH,
Yes, either LM5122 or LM25122 would do it. LM5122 has the switching frequency up to 1MHz while LM25122 is only 600kHz.
For the power level of around 500W, single phase is not enough. Webench does not support multi-phase design but we have…
Hi Roy,
There are several other relevant boost reference designs that could be useful here. You may want to check with your customer if this is a continuous power or peak power rating.
