Hello all I am trying to remove the CC pot (the one in the center, the 200k) and wire in 2 knobs one 200k for the coarse, and one 20k for the fine.
The photo below shows a general layout of the LTC 3780
The photo below shows the schematic of the circuit and the pot I am trying to replace.
The photo below is a high def photo (front view) with notes of the circuit board with the pots removed. Please note the left hand pot was removed and already has been replaced with a fine and coarse pot. I am trying to replace the center pot (value 200K) I drew the green lines, they are the traces on the front of the board, the red lines (best I can deduce) are the ones I drew for the traces on the back of the board.
This last photo is a high def of the back of the board.
If anyone can please draw me a diagram of how to add a coarse and fine pot to this.
Thank you
Ps. this is a completely different circuit and layout from the 1500w boost circuit I was working on. Please admin do not take down.
