Sync converters

One sync signal is for the horizontal, one for the vertical. There are three types of sync generation; separate sync, composite sync, and sync on green. Separate sync is when the sync signals are sent on two separate wires on the cable. Composite sync is when the sync signals are sent on their own, dedicated wire in the cable. Sync on green is when the sync signals are sent on the same wire, which is the same wire that the green color signal uses. The VGA standard uses a separate sync signal.

Sun workstations used composite sync. My Account. These converters already have a sync option so I think it should be possible to parallel them. Is this approach possible to reduce noise or do I miss something there? You're right about driving different converters power trains with different phases of a master sync clock. Doing so increases the ripply frequency on the output and thus makes it easier to filter.

But in your case, you need to make sure the individual converters allow themselves to be connected in parallel. If they do, it should be so stated on the data sheet. If not, you run the risk of one converter trying to supply all of the load current. I skimmed through the data sheet for the converter you referenced and did not see any discussion about operating converters in parallel.

I'm unsure that they can be connected in parallel and, for me, the only realistic option is to build one yourself using the LTC for instance : -. The picture above shows a 24 volt output capable of delivering amps so, re-arranging a couple of values to give 12 volts out isn't going to be a hardship. If you dig through the data sheet details you'll probably find that when operating with 12 volt on the output, the input voltage can be significantly lower than 36 volts too if that helps.

You can also buy a demo board too: -. I do think that, if you wan't to use just two devices in interleving mode with degrees, the module already support this without any other needs. Interleaving of switching can also be achieved for input noise cancellation. If MS pin is tied to Vin pin it will become a clock master. In this mode pin 32 SYNC will become a clock output that can be used to synchronize other i6A power modules. Shipped From. Quick Shipper.
