I'm trying to design a power supply for a class D, stereo audio amplifier based on the TPA3250. I have a transformer that will give me 35V on the secondary which I plan to rectify and smooth to supply the below SMPS. Is this circuit suitable to supply 36V up to 10A and am I likely to run into problems with noise?
Overall it seems OK. The 500kHz switching frequency should help with noise, although you can always add a second inductor/capacitor stage for further filtering. As long as you don't end up with broadband hash in the output due to noise in the regulator, and as long as it doesn't oscillate, I suspect you'll be fine.
Layout will be critical. You really need to think like an electron to keep the supply stable and to keep it from radiating.
