I have designed a Buckboost converter that converts from 48V to 59V with a current of 50A with CC/CV but in an open circuit at the output the LT8390 gets too hot and has a comsumption of 280mA. Any idea of the possible error?
Please make sure to follow layout guidelines on page 26 of the datasheet. You may also copy the layout of the demo board.
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.
this is the schematic, the components were selected according to datasheet and LTpowerCAD.
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.
