• 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

    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.

  • 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…

  • 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。

    对应的LTM4628原理图如下面2副图片所示:

  • 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,…

  • RE: AD9361发射

    还有一个问题需要麻烦你:我们在测试AD9361的clkout管脚时发现在中心频率两边有500K左右的杂波(如图),并且幅度比较高。但我们给1.3V供电采用的是ADP1755;数据端口供电2.5V和3.3V采用的是LTM4628,开关频率是760K。所以现在我们一直不清楚这个杂波来自何处,所以现在非常感谢你的帮助

    Hello Jim,

    I noted that 110mA is the quienscent current. Is there big difference between quienscent and the working current?

    Is it means that the +5V and -5V should have same current? Otherwise, if +5V can provide enough current and -5V can't, the parts…
