    Hello kazunorihayami,

    I have sent an email to you with the requested information. 

    Thank you!

  • About LTM4628

    Hi,

    Would you please tell me the saturation current value of the inductance integrated into the LTM4628?
    I am considering using the LTM4628 in 4-PHASE (Vin = 24V, Vout = 5V / 6A).

    Best Regards,

  • LTM4628 Vout of +5.5V

    Hi,

    I plan to program LTM4628 to output +5.5V. 

    In the features section of the datasheet, it mentioned it can do so.

    However on the power module description section it can only provide precise output voltage up to 5Vdc.

    Kindly confirm if I can use…

  • LTM4628 Vout

    Does the problem occur if the potential difference between vout1 and Vout2 is large?
    For example, Vout1 is the maximum output value, Vout2 is the minimum output value, and the frequency setting resistance value is Vout1.

  • Remote sense for LTM4628

    Hello,

    I'm looking at NOT using the Remote sense feature for a 5V VR from Linear Tech LTM4628.

    the datasheet specifies to GND the DIFFP when not used. What about DIFFN?

    do i connect to another pin in particular or float when NOT used?

    Thanks,

  • LTM4628 ouputs a sine signal

    why it doesn't output a DC power, but a sine signal?

  • LTM4628输入12V设置Vout1=0.85V,Vout2=5V,但是Vout2实际上输出11.54V(LTM4628 inputs 12V to set Vout1= 0.85v and Vout2=5V, but Vout2 actually outputs 11.54v )

    我按照输出电压和反馈电阻的关系,输入电压为12V,设置Vout1=0.85V(Rfb1=144.96KΩ),Vout2=5V(Rfb2=8.25KΩ),Rset=143KΩ,但是实际测得Vout1跟预期一致,但是Vout2实际输出为11.54V。当我将Rset换为60.4KΩ后Vout2实际输出11.66V。在更换Rset前或更换后Vfb1均为0.6V,但是Vfb2一直为0.5V。

  • Can LTM4628 support 24Vin and both 5V and 3.3V Vouts?

    Hello,

    My customer considering to use LTM4628 in their system.

    Their requirements are 24Vin , 5V with 4 A and 3.3V with 6A.

    In your datasheet , below application (Figure 32) is suggested, but when we do the simulation in LTSpice, we don't get simualtion…

  • LTM4628 inputs 12V to set Vout1= 0.85v and Vout2=5V, but Vout2 actually outputs 11.54V

    According to the relationship between output voltage and feedback resistance, I set the Vout1 = 0.85 V (Rfb1 = 144.96 KΩ), Vout2 = 5 V (Rfb2 = 8.25 KΩ ),  Rset = 143 KΩ . The input Voltage is 12V. The actual measured Vout1 was as expected,…

  • Can two different types of LTM modules be operated in parallel?

    I mean one LTM4628 and another LTM4628 placed like this, and they drive the same output at the same programmed voltage, is it possible?
