LT8390 too hot

Hi Gest,

Can you provide your schematic? You can verify your design through LTpowerCAD and LTSpice to make sure that your design is appropriate to the specs.

Please send the LTSpice file simulation of your circuit.

The simulation works properly but in the final circuit  the LT8390 gets too hot and finally the part breaks.

Hi gest,

Please make sure to follow layout guidelines on page 26 of the datasheet. You may also copy the layout of the demo board.
