  • TPS51206: VTTSNS Connection

    TI Thinks Resolved
    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…

  • TPS51206: Power off sequence

    TI Thinks Resolved
    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,

  • TPS51206: VTT behavior at power up

    TI Thinks Resolved
    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…

  • TPS51206: S3 + S5 Power State Control for DD4 1.2V?

    TI Thinks Resolved
    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.…
