Other Parts Discussed in Thread: TPS563202
I was targeting to use TPS563201DDCR, but I noticed is maximum load capacitance for stability was only 68UF for the tightly coupled capacitance (LC filter). I am concerned because other parts of my board would add capacitance that would exceed the 68uF limit.
I was planning to have additional capacitance on the targeted 5V rail a little bit away from the LC section. My understanding that other capacitance does not necessarily get factored into the LC limitation for stability. However, what I don't understand is how I define how far away my other capacitance would need to be for it not to affect the stability.
Also is there a new maximum capacitance that the part would then be stable to. For example could I have 150uF capacitance total on the rail.
There is the TPS563202 which seems to have double that capacitance but I am having a hard time telling the differences between these parts or if there is a better part for a 5V 3A supply for an input up to 14V
