  • 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…

    The LTM4637 schematic (U1A, U2A, U3A, U11A, U13A) look ok.

  • RE: LTM4637EV#PBF bulk capacitor

    If the regulator is kept very close to the FPGA, the 4# 680uF could serve as the output caps for LTM4637. Usually, these capacitance is enough for normal operation of LTM4637. But for the system, how much capacitance are needed depends on the

    specs of…
