  • RE: LTM4650 parallel operation for 300A

    Hello Joseph,

    Can you provide your email address and I will send you a LTPower CAD file for 300A operation.

    Is it for LTM4650 or LTM4650-1 or LTM4650A

    To generate a 300A template, blue box in the converter specification are required to be filled in.…

  • LTM4650 Switching regulator

    Hello Sir/Madam,

    we are using LTM4650 regulator in the configuration of two phase single output. When we gone through the application schematics, a feed forward capacitor is used externally in VFB pin. But there is no information about this capacitor…

  • ltm4650-1 there's an error in Vout

    12v transfer to 0.95v50A. there is an error in vout, vout got to 1.68v as the below picture.as u see, isn't any problem in my schematic ?pls help and give me some advice.

  • LTC2977 Triming status when DC/DC load transient

    Hi,

    We use LTC2977 to trim DC/DC(LTM4650) with an external feedback network.

    When the load transient, if LTC2977 exactly monitor the pulse (for example, 6mV diviation), if LTC2977 adjust its DAC to trim DC/DC ? Because the DC/DC will return back after…

  • 三个LTM4678电源模块并联使用,上电初始电压1.0v,上电完成之后要求通过PMBUS改成0.85v,在修改过程中,3个模块之间电压不一样,会不会出问题?

    需求:12v输入,初始电压1.0v,上电之后通过PMBUS改为0.85v,电流150A;

    当前设计:

    1、三个LTM4678电源模块并联实现,上电初始电压1.0v,上电完成之后要求通过PMBUS接口改成0.85v,但是在修改过程中,3个模块电压不可能同时修改成0.85v,肯定有先后顺序。如果第一个模块电压改为0.85v,但是余下两个模块的电压还没有改过来,这个是否有影响?是否有参考设计?

    2、如果第一种方案不行,是否可以用1个ltm4678+2个LTM4650,这样是否可以使用?有没有参考设计?
