Hi team,
My customer is using TPS54325, which uses DCAP2 control.
For general DCDC, it is purposeful to measure the frequency responce and check the gain and phase margin to know the system stability.
But for DCAP2 control, since these DCDC has an internal phase compensation circuit in it,
my customer thinks that the it is useless to take a frequency responce result for DCAP2.
Is this correct?
If it has a benefits for taking a frequency responce for DCAP2, could you explain why the result it usable beside the internal phase conpensation circuit.
Regards,
Ohashi
