MPQ9843-AEC1 querry and MPsmart model request

DC-DC Power Converters
1

Hi team,
I will be working to generate 9 V output from an input voltage range of 11 to 16 V. Is this possible with MPQ9843-AEC1?

How to calculate required Vin(min.) for MP9843?

Can I get a MPsmart model for simulation?

Thanks

Thats pretty cool, there is absolutely no way to figure out what the minimum input to output differential can be. In fact there is no spec on max duty cycle, maybe it is zero and this thing can’t work at all. A more careful datasheet would give a max duty cycle line to allow you to figure this out. Looking at the block diagram I would say it ought to be able to go to 99% DC in which case you should have no problem, but you cant point to anything backing up that assertion.
