Part Number: UCC29002

Greeting,

I are prototyping of load sharing in one of my school project. I had selected UCC29002 IC to have my load sharing effect. The buck converter im using are LTC3891

May i know how to i connect the UCC29002 with the sense pin of LTC3891 ?

Hello wei jing chen,
The first think you need to do is read the data sheet for the UCC29002.
Then you should read the application reports and study the reference designs.
All of this preliminary information is available on the web page

HI,

thannk you. i have any question. In the datasheet of UCC29002, it mention about " ΔVADJ = maximum output voltage adjustment range of the power modules to be paralleled " what does this mean?

Meaning it is set by us, or every power module have it own ΔVADJ ?

This is the range of adjustment that you can get from each module. For example you may be able to get 12V output with a 5% adjustment capability.

hmmm, is there anyway i can know or see the range of adjustment giving by my module ? my output is 10V

Oh and another question i have is that if i am removing the (shutting down Controller) function which consider of BJT and resistor, can the same calculation step be use that is provided in the MathCad PDF??

Yes . Use the calculator for this step.
