  • LMR38010: My LMR38010 design doesn't seem to work above 55V.

    Part Number: LMR38010 I am using the LMR38010 switcher design to regulate to 12V. I am having an issue when my input voltage increases above 55V, the switcher becomes unstable and gets very hot. Below 55V and it operates fine. All my capacitors are rated…

  • LMR38010-Q1: LMR38010-Q1: no feedback network compensation required?

    TI Thinks Resolved
    Part Number: LMR38010-Q1 Other Parts Discussed in Thread: LM5164-Q1 , , LM5163-Q1 , LMR38010 Dear all, I noticed that LMR38010-Q1 doesn't apparently need any feedback compensation network, such as the one required by its older 'brother' LM5164-Q1.…

  • LM5163: LM5163 and LMR38010 current entering SW pin when disabled

    TI Thinks Resolved
    Part Number: LM5163 Other Parts Discussed in Thread: LMR38010 Hello, I was wondering: what is the behaviour of LM5163 and LMR38010 SW pin when some current is injected on Vout (from 0mA up to 50mA), with Vout=0 i.e. when Vout rail is pulled up by an external…
