Hi all
Would you mind if we ask TPS54327?
<Question1>
The value of output capacitance is 22uF upto 68uF on the datasheet.
How much is the maximum value? Upto 200uF??
And in case of Cout=200uF, should we care followings?
-Phase margine for stability
-Soft start delay
-Pre bias start
<Question2>
In relation to <Question1>, for example, there is 10uF or 22uF ceramic cap in the subsequent stage circuit.
There are three subsequent stage circuits, 10uFx3=30uF.
In this case, does it(ceramic cap in the subsequent stage circuit) include total amount?
Usually, We guess that the total amount(output cap value) includes the subsequent stage circuit.
In this case, when our customer uses Aluminum cap(large ESR) at the subsequent stage circuit, transient responsiveness will decrease, right?
And we guess that it depends on distance(impedance) with the subsequent stage circuit.
Kind regards,
