LTC3676-1 gets Over Heated in i.mx6 quad

Question

I am testing LTC3676-1 for i,mx6 quad. 
 However, each BUCK regulator generates a lot of heat and the output is not coming out properly. 
 I met the specs enough to meet the regulations, but I don't know why this is happening. 
 Please advise.

Hello, 
 Thanks to your advice, the problem was easily solved. The problem occurred because the Buck Reg coil was incorrectly mounted on the PCB. 
 The coil's resistance value was too small to check, so this happened. The coil has been remounted and the LTC3676-1 is now working fine. 
 Due to the recent short problem of parts, I made a quick design change and made a new board, and thanks to you, I solved this problem well. Thank you again. 
 kind regards
