Forum Post: RE: Not sure design guide recommendations exist?

Tom,

I have similar question wrt providing enough bulk capacitance for a lower power C6657 (dual core).  In HW Design Guide, page 25, CVDD recommends 1663uF minimum for 10W solution.

If customer is going to be ~3.5-4W, can you do a simple calculation of [4/10 * 1663] = 665.2uF?

If this does not apply, can you suggest how to adjust the min, bulk capacitance for ~3.5W C6657 design.

Thanks. Marc
