Part Number:TPS544C20
Hello,
I have a question for TPS544C20 EVM.
I measured transient response of 0A to 10A transient on the EVM
Then I could see about 35mV drop like the below figure.
I added 10pcs of 100uF on VOUT (5 pcs for TP11-TP7, 5pcs for near C18/19/24/25) to reduce the voltage drop.
But the voltage drop waveform wasn't improved at all. I could see almost the same waveform.
Do you understand why the voltage drop was not improved at all with additional capacitance(100uF x 10pcs)?
Regards,
Oba
