hicookie, I noticed that you typed "5kohm vr" in your text, but the graphic shows 50k ohm vr Just bringing it to your attention in case you want to fix it

give a resistor between this 2 pin, you can fix loadline calibration

prepare a 5kohm vr, connect to Pin#16 & Pin#17
using meter to measure it , oringinal should be 45.5k
turn it to 1.5~1.8k, depend on what loading.
