  • TPS63805: Analysis of the SW2 pin overshoot on the TPS63805

    Part Number: TPS63805 Regarding the TPS63805 SW2 pin: on my board, during operation, I measured a negative undershoot of -0.7 V on SW2, with a duration of over 200 ns. Is this acceptable? I couldn't find any specification in the datasheet

  • TPS63805: Cannot able achieve the boost functionality with TPS63805 PSPICE File

    Part Number: TPS63805 Hi, I am doing EMC simulation with Ansys tool involving TPS63805YFFR part number. I have downloaded the unencrypted PSPICE model from TI website and used it in my simulation. I getting proper buck functionality with the PSPICE…

  • TPS63805: Any FMEA report on TPS63805?

    Part Number: TPS63805 Hi , My customer would like to have the FMEA report to understand the possible root cause of i nput of TPS63805YFF to be shorted (15 ohms) to ground. Thanks, Christina

  • TPS63805: inductor change

    TI Thinks Resolved
    Part Number: TPS63805 TPS63805's datasheet recommends XFL4015-471ME as an inductor. This inductor has a very high current and is expensive. My design has a maximum current draw of 1A. Due to this, I feel XFL4015-471ME is overkill, and I want to use CIGW160808EHR47MLC…
