Hi Ishiwata,
The best counter measure is probably to control S3 and S5, as mentioned above and as you saw. Not sure if this is what you meant by adjust the fall time.
Shuji Ishiwata said: Also, it does not occur if you change DISCHARGE MODE from Tracking…
Part Number: TPS51916 Hi Team
My customer spestech use TPS51916 in industrial PC, for DDR power supply.
When VTT power up, the PG drop can be tested, it will last for 1ms. below is the waveform, red line is PG yellow is VDDQSNS.
schematic is also attached…
Part Number: TPS51916 Other Parts Discussed in Thread: TPS51216 , Hi team
There is one question related to our legacy device TPS51926A.
The background is customer has some stock of our old device and need to use up them, so they use TPS51926A in the same…
Part Number: TPS51916 Hi
My customer have few questions as below,
Why the TPS51916 need to support Hi-Z in S3, what is this feature help?
Why the VDDQ need to support sink and source?
Part Number: TPS51916 Hello TI Support Team, I am using the TPS51916 in a DDR4 application (1.2V) in DCAP-2 mode with tracking discharge - Mode 0 (using 1kOhm resistor at R7 in schematic photo below). Targeting 6.5A as my limit of the output current.

Part Number: TPS51916 Hi Team,
My customer is working on a DDR3L power supply design that will use the TPS51916.
We have come up with some questions:
They have been mostly using Webench as a basis for the design, and had a question on the implementation…
Part Number: TPS51916
Good day Colleagues,
My customer is using the TPS51916 for DDR4 and likes this part.
Now he got RDIMM memory size increased and asks if the part can supply up to 24A of output current.
He says Webench has 20A of output current limitation…
Part Number: TPS51916 Hello TI Support Team and Community,
I am working in the standard Cadence PSpice, and not the PSpice for TI variant. There appears to be an issue with the bias point in my schematic and possibly an issue with the model. The VREF voltage…
Part Number: TPS51916 Hi Team,
When the IC was powered on, the Ivtt source current was 5.6A peak inrush current. (The width of the peak is about 5us.)
The source current limit is typ.3A, but the current is larger than that.
Isn't it assumed that the…
