Hi Mitchell,
As you say the UCC29002/1 is not available in DIP package but for your testing it is possible to solder the surface mount package into the DIP solder pads.
It looks like you can get samples of this part here:

Hello Martijn,
It should be possible to use the UCC29002 with this power module. I say should because the schematic for this module is not available.
Normally there is a resistor between the + sense pin and the +Vout pin. You will need to measure this…
Hi expert,thanks for fast reply. I've read the discussion but some things seemed a little bit strange.
Why can we not use synchronous rectification if we parallel the psu's? the designer in the discussion has a voltage range wich is at 80V but i had…
Hello Han Lee,
You are correct about the voltage rating.
For output voltages greater than about 12V the Figure 5 of the data sheet.
The NPN transistor will limit the voltage on the ADJ pin to the voltage set by the value of the midpoint voltage…

Document slua610.pdf deals with UCC28950 startup into a pre-biased output, which will occur when multiple outputs are paralleled together. As shown on page 1 of the document, an external load share controller such UCC29002 is required to implement…
Hi User,
unfortunately we do not have such simulation document for load share controller.
I would suggest you can download the excel version or mathcad version calculator for the controller. it should be enough for the design.
below is the link…
Hi Tim
Glad you found my answer useful - here are my thoughts.
1/ If the input voltage is going to be greater than 105V then the UCC28951 is a much better solution. If the input voltage is less than 105V then it's a bit more evenly balanced and comes…
Hello Kai
The UCC39002 is a general purpose load share controller and it can work with ANY power module providing that the module has a remote sense feature. If the module has a trim up/down facility then the UCC39002 can control it too. If the module…
Hi,
The statement you posted was taken from an old revision of the data sheet (SLU495H) and it not correct.
It was corrected in the latest revision.
I am pasting this line from Section 3 , second paragraph of the UCC29002 data sheet (SLUS495I) …
Hi Anbarasan,
The connection between one primary full bridge and one secondary full bridge you showed looks correct.
From my point of view, this type of connection works well only if the two controllers are placed on the same board, or the distance…
