    Is it possible for LTM4637 to generate negative output?  eg:12V input  -5v output 20A?

  • RE: LTM4637 negative output

    The maximum input voltage is 18V of LTM4630, so I don't think it is suitable for 12V input & -5V output(20A). In this case, I think it would be better to use two LTM4638 than two LTM4637, because LTM4638 is cheaper than LTM4637. Am I right ?

  • LTM4637:Satbility in light load

    Hi,

    I checked Phase Margin (PM) using LTpowerCAD about LTM4637.

    I loaded default solution in LTpowerCAD.

    When Iout = 20 A, Phase + 180 deg is enough in all frequency.

    When Iout = a few A, 

    Iout = Aの場合、PM > 70 deg

    However, Phase + 180 deg < 20 deg @ …

  • RE: 如何利用LTM4601/02,LTM4637输出负电压?

    You are right. Buck uModules can be used to give negative output voltage.  LTM4601/02, LTM4637 can all be used in these applications. 

    The output of uModule should be connected to system GND and GND of uModule connect to -Vout. This is a buck-boost configuration…
