PowerCompass Multi-Load Configurator
Example of Open Design Template
To get started here, I'm just going to go ahead and load in this example template here. Pick it from the list and then hit the load template. And when this loads in, we'll see what we get. Okay, so you can see it loaded in the example template and we have set this up where we rename the system rail, the Sys_12V. If you rename rails, which you can, your outputs, just they have to be unique names, otherwise you'll get a notification that names can't be duplicated.
So in this case, we set up a 12-volt input, 5-amp supply and then we've set up a bunch of voltage regulators off of that, core rail supply there. So, here, you can see we set up a 1.5, 19.6 amps and then so forth. Then we also created an LDO supply to buck the voltage going into two LDOs down to a lower voltage, which is being connected to the VCO and VCO2. So you can see these are connected to LDO supply. There's also an indication out here that tells you that this rail or output is feeding to a secondary supply.
Another nice feature is we build a block diagram. So you can see you have your main supply coming in at 12 volts that shows all your different name of your outputs and their voltage, and current output, and also their sequencing up and down. You can also see that the VCO and VCO2 are there that are secondary off the LDO supply.
Okay, next thing. If we were looking at this, we would say, "Okay. Why do we have two LDO supplies that are the same voltage, different currents, they have the same sequencing?" So in this case, if you had optimize solution turned on, it would basically collapse these into one LDO supply because all of the rail sources are same. They're both can be a source in from LDO supply. They both have the same voltage. The currents can be summed together. They're both LDOs and they have the same sequence.
So, as an example, I will show this. We can either run this on, if it's turned on, on optimize solution, when you hit "find parts," then it will automatically optimize all of the rails down here. You can manually run this by just clicking the plus button and then you can undo changes by clicking the minus button.
So as an example, I'll just manually run it here by clicking the plus button and you'll see what it does. It will collapse those two LDOs into a single LDO, and then it combined the names together for those two supplies, and it summed the current, kept the sequencing the same. So our block diagram is updated to show that it's now VCO, VCO2.
So this can be helpful, but in other cases it could be something you don't want enabled if you have your system laid out exactly the way you wanted. And maybe in this case, you needed two separate LDOs because of board location, where they're at or something. So in that case, you could turn off the optimization and like say, we could undo this optimization by clicking the minus sign if we wanted to.
I'm going to go ahead with the next step and show you a Find Part. I'm going to go with this optimized layout here that we just did and I'm going to hit "find parts."
