  • TPS54394: The abnormal softstart waveform analysis of Vout.

    TI Thinks Resolved
    Part Number: TPS54394 Hi expert, My customer found the issue about softstart waveform, which has unsmooth ramp up scenario. I also find the scenario in TPS54394 datasheet Fig. 11 as bleow red square frame: My custmoer meet the issue in -25℃, 25 ℃, but…

  • TPS54394: p2p difference

    TI Thinks Resolved
    Part Number: TPS54394 Other Parts Discussed in Thread: TPS542941 , Hi team, what's the difference between TPS54394 and TPS542941 aside from the current rating and Rdson, are they BOM to BOM if the loading is below 2A, anything I miss?

  • TPS54394: Design feedback

    Part Number: TPS54394 Hi, Please could you give me some feedback on the following design. TPS54394 1V1 @ 3A 1V5 @ 3A Most parts have their ratings on the schematic. L1 & L2 = ABRACON ASPI-6045T-2R2N-T Here's the layout: There are internal layers…

  • TPS54394: Inductor peak current

    TI Thinks Resolved
    Part Number: TPS54394 Other Parts Discussed in Thread: TPS62130 , TPS62903 Hi, Looking at page 14 of the datasheet the peak inductor current is calculated at 3.46A. Trying to replicate the design in webench, I get a value L Ipp of 2.08A. Can you advise…

  • TPS54394: TPS54394 example layout is bad

    TI Thinks Resolved
    Part Number: TPS54394 It's funny on one thread regarding this part, someone said the user's layout was very bad because the switch node was connected to the inductor using a different layer. That is the (poorly) recommended layout on page 16 of the data…
