Tool/software:
Hello Team,
I'm using the TPS54202 in my design to step down 12V to 5V (1A).
Now, I want to reuse the same IC for a new power requirement: stepping down 12V to 3.3V (1A).
This 3.3V output will power a micro-controller and some sensor applications.
In the existing design, the inductor used is 22µH (Isat - 1.7A). Can I use the same inductor with a modification to the feedback resistor to get 3V3?
When I simulate in Power Bench, it suggests using a 3.9µH inductor.
My question is, what will be the impact if I continue using the 22µH inductor instead of the 3.9µH for the 3.3V output?
