  • LM5009/SM72485 transient response

    I have an automotive application that has a load dump requirement that will result in a rapid rise of input voltage - how well does the feedback loop on these deal with this?

  • SM72485 / LM5009

    Other Parts Discussed in Thread: LM5009A , SM72485 , LM5009 Dear Sir May I know what's different between LM5009 / LM5009A / SM72485?? I don't know which is TI focus and popular solution Thanks

  • LM5009 Conducted EMI

    TI Thinks Resolved
    At high Vin >70V it is not possible to use tantalum capacitors at the Vin pin to control conducted EMI, what solutions are recommended ?

  • RE: re: LM5009 Damage on High Voltage Power Up

    Hello Marc, While you do the fast startup tests with the LM5009 for VIN > 70V, would it be possible for you to capture a waveform snapshot of the voltage at the VIN pin of the part? In that way we can confirm how fast a VIN slew rate does the part sees…

  • LM5007/LM5008/LM5009 won't regulate and runs hot

    Hi, I am using the LM500x series to buck a 48V battery down to 5V, however whenever the converter is loaded it will not regulate its output voltage correctly and it will sink a significant current resulting in the converter running very hot. Whenever…

  • LM5009 data sheet shows an ES3D catch-diode, but elsewhere the TFSL1100 is specified ? Which is preferred and why ?

    Other Parts Discussed in Thread: LM5009 There seems to be some differences between the data sheet suggestions for the catch diode and other examples in the literature. I am looking for a best conducted / radiated EMI solution (rather than best efficiency…
