In the datasheet, I noticed the equation for I_limit is 1675/(R_Imon*Rsense2). It says that those 2 resistors set the average current limit, yet if I plug in the values for the circuits found under "typical applications," the current limit does not come out to the amperage spec'd at the output (i.e., page 38 shows 10A supply, but I_limit comes to 12.9A). Why are these values different?
I am wondering because I have a DC2814A-A demo board, and current at the output says 3A, but I_Limit comes to 6A and I don't see anything limiting my output current except the ferrite beads which are 2.5A.
My name is Chris Gass. I am the product application engineer for the LT8210. I also designed the DC2814A demoboard.
We designed both the circuits on the datasheet and the demo board to support,…
