Brian, TAS5630 requires single rail supply voltage, 48-50V and probably aux. voltage for bias and housekeeping circuitry, depending on the board implementation. I suggest to use the SMPS500RS-48V version, since this power supply can deliver the necessary current to supply such amplifier which normally would deliver up to 2x250W.

The 2x300W stated power is just marketing statement, and is given at ~10% THD or more. That's no music anymore, just acoustical garbage. the TAS56030 can deliver at most 2x250W with reasonable TDH (up to 1%) Most of the IC's manufacturers use to state their power levels at 10% for obvious purposes. When the marketing managers or so called "Project managers" from a given company make the choice of the parts which will be used in some future product, their eyes stall at the first power statement, the large font, bold one, without bothering to read further where the real power in real conditions is barely mentioned.
TDA8950 is declared to be able to deliver 2x150W but at reasonable distortion level, it barely offer more than 2x100W. TA3020 is another good example, the maximum achievable power on 4 R impedance on each channel without the risk of blowing the ic is ~450W. I am more conservative and i supply the IC from a regulated smps which delivers +-61V where can get 400W with low THD. but even if is supplied at absolute maximum voltage of +-70V cannot deliver more than 500W, as i saw on many places that some declared that their amps can deliver 600W, 800W or even 900W in SE, 4R. Do the math, to catch the lie..

Yes, I bought one of the same boards as Brian and didn't realise what was behind the quoted 2x 300W figures until after I got it.

With the 4 ohm floor standing speakers I have, it sounds nice up to about 150W (which for the price I'm still happy with). It's using a MW 400W PS.

I'll be giving one of your amp modules and SMPS a try for the next project.

Hi Cristi,

Hi Cristi,

1) What are the dimensions in term of (WxDxH in mm) for SMPS2000R (2 rails) and SMPS3K6QR (2x2 rails) respectively?
2) Is the main voltage output regulated at 10% tolerance with unregulated auxiliary output?
3) Is the output voltage (both main & aux.) configurable to meet custom design without additional charge if within your ranges?


Thanks!
Tom

Just mounted the 180 in a LM3886 based. Love it...

Great stuff and great value for $$

Thanks Christi.
