Hi all,
I'm currently trying to use the LT8708, in order to power a board. I'd like it to have a nominal behavior (buck/forward mode) where Vin is between 32 and 60V and Vout is 12V. But under certains conditions it should be able to switch to reverse mode (boost mode) with Vout becoming the "supply" voltage (still 12V) and Vin being supplied by the LT8708 to a level of 32V.
Following datasheet to chose the different components of the sub-circuit, I've reached a part where I'm selecting the Inductor. At this time there's a formula to compute the minimum inductor in boost mode : 
I was wondering if, in my case, Vout (of the datasheet) would be my Vin and Vin my Vout or not. In that case I can compute L because Vout = MyVin = 32V and Vin = MyVout = 12V and condition Vout greater than twice is reached but if I don't switch then Vout is not twice Vin and I should not calculate L ?
Have a nice day,
Will.
