refering to the same question sir, i've given input to power management tool as vin=12 vout=5 iout=20A . i've got those above part or components as suitable to hdd needs they are :
DC/DC Controller (External Switch)
TPS40193
…
1/10 of the switching frequency is a good choice.
The bandwidth corresponds to how fast the loop response is, so higher bandwidth means the output voltage can recover much more quickly during load transient.
Here is a design tool/checklist to help verify…
Hello Anthony,
Please provide the updated TPS40KType spreadsheet that you used prior to making the last recommendations for the compensation network values.
Please see attached.

When the same control signal is used to enable two TPS4019x, it is not suggested to tie the ENABLE pins of the two TPS4019x together. The reason is as follows. Due to the process variation, the threshold on ENABLE pin which is 1.9V typical (3xV BE ) is…
