UCC39002: How to Integrate UCC39002 with a Power Supply Lacking Remote Sense Inputs

Tool/software:

I am designing a power supply system that incorporates the UCC39002 load share controller. My power supply currently uses a standard feedback topology with a single resistor divider network connected to the output voltage (Vout) for regulation. It does not have dedicated remote-sense inputs (positive and negative sense lines) to measure voltage directly at the load terminals.

The UCC39002 documentation specifies that the power supply must support remote sensing to properly implement load sharing. Given that my power supply lacks remote-sense inputs, I have the following questions:

1. How can I adapt my existing feedback network to work with the UCC39002?

   • Can I derive the equivalent of a remote-sense signal by modifying the feedback circuit?
   • Would it be possible to add external sense lines or simulate them with minimal changes to the design?

2. Is there a recommended circuit modification to couple the UCC39002 with a power supply that regulates locally using a resistor divider?

3. What challenges or limitations should I expect when using the UCC39002 in this scenario without traditional remote-sense lines?

Any guidance, application notes, or design examples for adapting the UCC39002 in this type of setup would be greatly appreciated.
