Hi David,
I agree with Field that some scope captures from the working board to show how the input signals are ramping up and the timing between each one would be good to have.
If you have the capability, an A-B-A swap of the IC on the working board and…
Part Number: TPS51206 Other Parts Discussed in Thread: TPS51200 Hi ,
We are planning to use TPS51206 in our design for powering x8 DDR4 13 Nos.
We have earlier used TPS51200 in other projects for DDR3.
TPS51200 has undervoltage lockout value of min 360mV…
Part Number: TPS51206 Other Parts Discussed in Thread: TMDS64EVM , TPS51200 Hello team,
I am confused on power on sequence of this device.
On datasheet 7.3.6, it says "During power on, it is allowed to turn on VDD, S3 and S5 first, then turn on VLDOIN and…
Part Number: TPS51206 Hello team,
I am confused which configuration I should use.
On 8.2 Typical Application section, there are 2 configurations.
Figure 24 is "VLDOIN = VDDQ Configuration" and Figure 27 is "VLDOIN Separated from VDDQ Configuration"…
Part Number: TPS51206 Dear Tech Support Team,
The customer would like to confirm the date code based on the top markings.
Could you please help to check and advise on the correct date codes? Thanks.
Best Regards,

Part Number: TPS51206 Hi Team,
The data sheet, 8.2.1.2.5 VTTSNS Connection section, says as bellow. "Consider adding a low-pass R-C filter at the VTTSNS pin in case the ESR of the VTT output capacitor(s) is larger than 2 mΩ.The R-C filter time constant…
Part Number: TPS51206 Hi Team,
According to power off sequence on the data sheet, it says that VLDOIN should be ramped down before VDD. However the customer system, VDD(3.3V) ramp down before VLDOIN (1.2V) ramp down. Is it no problem?
Best Regards,
Part Number: TPS51206 Hi Team,
In the customer system, the attached waveforms were observed at power up. Please see it.
VTT turns on with 2-steps, it rises to around 580mV first, then it rises to around 628mV. Is this a problem? If yes, please tell me a…
Part Number: TPS51206 Hi all,
I am investigating the use of the TPS51206 for a DDR4 application at 1.2V logic. Section 7.4.1 of the datasheet lists the power states needed to control the device but I have a few questiosn regarding these two pins:
1.…
Part Number: TPS51206 Other Parts Discussed in Thread: TPS653850A-Q1 , I am powering a DDR with a PMIC with the following part # ( TPS653850A-Q1). I have seen the DDR4 I am using has slew rates for the VDD and VPP supplies, and am wondering if the VTT which…
