  • TPS65220: TPS6522053 VSYSpor_rising & VSYSuvlo_falling

    TI Thinks Resolved
    Part Number: TPS65220 Hello , I'm checking the behaviour of TPS6522053, especially related to VSYS rising & falling. Into the datasheet are mentionned : VSYSpor_rising [2.2V.... 2.5V] VSYSuvlo_falling[2.175....2.25V] So according the below state…

  • TPS65220: Voltage Dip Issue

    Part Number: TPS65220 Tool/software: Will the Auto-PFM mode of the TPS6522053RHBR PMIC cause its output voltage rails—both the Buck converters and LDO—to momentarily drop during startup? During power-up, a voltage dip is observed on all PMIC output…
