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

  • LTM4637: Output instability

    Hello all,

    I have designed 1V core voltage for FPGA in my board using LTM4637 uModule. Below provided the circuit of the regulator I have designed.

    In one board out of two, whenever I am pressing the test point or even PCB, I am observing a sawtooth…

  • 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 = 数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…

  • 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

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

  • RE: About the thermal resistance of LTM4605

    Hi Hiro,

    Please check page 18 of datasheet. It list theta-JA values. All based on the actual PCB implementation using demo board. I'm not sure if we have other info that this. Please connect to local ADI sales team if you need the other data.
