TPS59641: TPS59641 Vcore for VRD12-IMVP7 tool measure VID between Mosfet csd87330q3d and csd87334q3d

Part Number: TPS59641
Other Parts Discussed in Thread: CSD87330Q3D, CSD87334Q3D,

Hi sirs,

We test the VCC(Vcore) dynamic VID measurement change Mosfet from csd87330q3d to csd87334q3d

test condition:

Vmax 1.150 V
Vmin .7 V
Static Icc  5 A
SVID Dn Slow
SVID Up Fast
High PS 0
Low PS 0

csd87330q3d VID:

Voltage change 5us after ALERT to settled is 9mV,it is pass spec 11.3mV.


Voltage change 5us after ALERT to settled is 75mV.It over spec. 11.3mV.

The change of Dynamic VID with csd87334q3d is too slow.

Rcomp (R363) is 13.3K now.

We try to change the value 20Kohm and 8.2kohm.

But the change of Dynamic VID is still slow.

Please help to explain why the MOSFET csd87334q3d is too slow ???

Then apply the solution how to adiust the Dynamic VID with csd87334q3d??
