LT8650S.pdfI realized a board with LT8650S. The schematic is here attached.
My idea is to have two different OUTPUTs VH and VL_I from the LT8650S. The max current for VH will be 1.5A and the max current for VL_I will be 0.5A
In this circuit, I can change the two output voltages by set the voltage (0 to 5V) in the points CTRL_VH and CTRL_VL_1 and so the OUTPUT voltage can vary from 23.9V to 3.83V.
My problems is that in the first application the LT8650S was burned.
Could you check the schematic if you see something wrong?
I would not recommend the same circuit design for such a wide output voltage range.
That being said, your inductance values are too low for high output voltage applications.
Thanks for the answer.
Could be Inductance value too low destroy the LT8650?
Hello,I'd like to understand what happened to my LT8650S when it was burned and so I'd like to have some information.Which is the max suggested output voltage when the Vi=24V?From LTPowerCAD (picture here attached) I saw that when the Vout is near Vi, the DiL/IC field comes red: is this the limit for the Vout?Looking forward to your answers.Thank you, Nick
