Part Number: TMS320F28P650DK
Other Parts Discussed in Thread: TIDM-02014

HI Zackary ,

TIDM-02014 reference design | TI.com I am not able to locate firnware for this reference design.

See my answers in green to your question

What PWM frequency and count mode (up-count or up-down) will you use for the PSFB?

Switching frequency is 20 KHz and its in Up -down count mode.

Whether you need blanking window functionality to filter noise during switching transitions

Yes ,it is necessary to have blanking functionality

Whether CMPSS DAC synchronization with ePWM events is needed for dynamic threshold adjustment

Yes , CMPSS DAC synchronization with ePWM events is needed

Thanks and Regards,

Hi Prashant
Is this thread a follow up to any other thread?
If above questions are requirements for your application, you can refer to "tidm_dc_dc_buck" solution in Digital Power SDK. This solution demonstrates peak current mode control and its configuration.
Thanks
