In other words, you could make a simple PSU using a transformer, perhaps using a Bridge rectifier (or 4x Schottky diodes) followed by a large value filter capacitor, then connect it directly into the input of a LT3045 PCB.

This makes them superb for powering end of chain low power devices, so the 500ma is adequate for these devices. There is much discussion about achieving 1-2 and 3amps but I have not needed that much. I power sets of LT3045s with a modified Teradak DC-30W (replaced caps with Nichicon HWs) into an Aqvox switch/USB 5v line/LPS-1 and finally into a Bluewave USB to Spdif board (which Micael/cornan and I have raved about many times). The already low 0.8µVRMS drops even more when put in series. I use for instance 7.7v boards into 5v into 3.3v. The main benefit of the in series boards is increased enjoyment! - deeper bass, smoother treble, cleaner spacious sound and expansive soundstage among other qualities. The drop out can be a couple of volts but must be more than 260mv and I recommend the fixed voltage ones. Highly recommend them if they fit your requirements.

For the less experienced members, the results are of course governed by the actual reference voltage of the voltage regulator I.C. used, not so much by the actual measured resistance values of the close tolerance resistors (1% or better) when used with a less precise voltage regulator. (Most DMMs don't have enough resolution to accurately measure close tolerance low value resistors) Kind Regards Alex Warning - Information Overload. (An experienced DIY person can also further reduce the voltage difference of the higher voltage output regulator by retro fitting a parallel metal film resistor of > 100 times the value across the higher value resistor of the 2 voltage setting resistors, usually under the PCB. If the Voltage regulator uses through hole resistors, it is possible to slightly increase the output voltage of a voltage regulator by replacing the lower value of the 2 resistors used, with a 1% resistor that measures a fraction lower than the original. You can also reduce the output voltage slightly by slightly increasing the measured value of this resistor, or decreasing slightly the value of the higher value resistor of the 2 voltage setting resistors. With the latter, you can also use a very high value (>100 times) resistor in parallel with it instead of replacing it.) Susumu SMD.

Useful to see he found Susumu to work ok. When I first tried some SMD resistors in the interest of keeping leads short in a feedback loop (I could solder them right across the device's pins), I tried some 'thick film' ones thinking they'd be better. Not so, the thin-film ones turn out to be the SMD metal films. The particular Susumu line I tend to use are the RG. Generally when I'm building something using SMD R's, I'll sub them in even if the BOM shows something else.

sandyk Posted January 1, 2018 Share Posted January 1, 2018 Hi Greg I have deliberately avoided using SM resistors where possible due to the need to easily measure the values of the resistors often sold on quantity strips,(fiddly) as well as difficulty sometimes reading the marked values. I have also had poor past experiences with their resistance tolerance %. One version of the PSU PCB (no trimpot version) that I use extensively in my DACs and Preamp etc. that was designed by DIY Audio member Greg Erskine also has provision for a couple of SM resistors in the voltage setting area, where these Susumu resistors would have been ideal ( trimming purposes) It can also use either through hole or SM diodes such as the ES1D, (which I have used) in the bridge rectifier section.

agladstone Posted January 2, 2018 Share Posted January 2, 2018 On 12/31/2017 at 2:39 PM, gstew said: Jean-Michel, You are very welcome. & I had planned to start out this set of replies with an apology on implying that one could get 3A out of 2 LPS-1's in this setup. You are very correct... and I apologize for not being clearer. The dual 3||LT3045 boards each have a max output of 1.5A and in parallel (when tightly matched) will provide 3A. BUT the system current will be limited by the LPS-1's 1.1A max each, so total out available is 2.2A. All very sufficient for a device that draws less than 500mA, but I'm an overkill kind of audiophile! As for improvement, I have AFAIK the only pair of LPS-1s that have been output-matched for paralleling (thanks again, Superdad!). I tried them in parallel to power either a Raspberry Pi I2S-output renderer or an SDTrans384 SD card player. I describe my initial experiences here: and an update after trying a dual 4||LT3042 board (800mA max per side, 1.6A max when parallelled) with each side powered by an LPS-1. That has been my reference for both of these applications since then. My gut feel is that the lower noise provided by these boards along with the additional energy storage (there's about 36,000uf on each board) are what make them better than raw LPS-1s for this application. I should add that in some other applications (such as Ian Canada's R-Pi Isolator board and Allo.com's R-Pi Isolator board and Kali reclocker board), I have tried both an Acko AKR75 regulators (his previous version using an ADM715x chip... next best chip regulators I know of after the LT3042/45s) and an older generation Belleson regulator between the LPS-1s and the load board. In these applications, I preferred directly powering them from the LPS-1 without the intervening regulator boards. That MIGHT change if I try an LT3045-based regulator board, but that is my experience so far. Pix of a couple of the AKR75 reg boards attached... agladstone, See my comments and apologies above. Powered from 2 LPS-1s, the max current you get from that setup is 2.2A. AND it takes care to match the board outputs (and should be done under load, as John Swenson said). So not easily today. For what is out there now, I'd look at the Vinnie Rossi supplies. Hopefully we'll see some new products soon that will make this more easily done. Also see Cornan's comments below on the real-world current draw of that DAC. I should add that I run a DIY Soekris DAM1021 DAC from the I2S output of the SDTrans384 SD Card Player. It is my reference setup. I have set it up to be powered either from a pair of very good DIY'd linear power supplies OR a pair of LPS-1's set to 7V. While the LPS-1's exhibit some fine qualities in this setup, I've stuck with the linear supplies due to slightly greater dynamic impact and shading. You have to understand I LOVE LPS-1's and have 10 of them around here currently. They are ground-breakingly great supplies. AND I have found some situations where I either find them better augmented (such as feeding the dual 3||LT3045 or dual 4||LT3042 supplies) or where I prefer a different solution. Still, in MOST cases, I can't beat them! Pictures attached... I should add that I use different input and output capacitors than what is listed in the BOM... these are the same line as those used in the dual 4||LT3042 boards that have also worked very well where I've used them, but alas are no longer available. I also: 1. Added an additional 5,600uF capacitor at the output of each side. 2. Omitted the rectifier diodes and jumpered as appropriate to make them DC input. 3. Left out the heat sinks for this application due to both the low current draw of the driven device AND a fairly low input voltage (7V out of the LPS-1s). 4. Used .1% resistors instead of a pot to set the output voltage for each side. Jean-Michel, I left out the Shottky rectifiers & jumpered across traces to make these DC input... see pix of my unit. Greg in Mississippi Thanks! All of this is way over my head! I think for me it’s best that I stick to either finding a Vinnie Rossi DC4EVER (he is no longer making them) or just get a much better Linear power supply than my current HDPlex! I’m comfortable making my own DC power and JSGT grounding cables with the screw down connectors, but that’s about as far as my DIY capabilities take me at this point!

I'm not keen on being in the cable business (was in the past; might be again in the future), so was fine with his desire to just put it out there. But I admit to some chagrin regarding his idea--and his name--being used without permission for profit by an overseas firm. Live and learn I guess...
