• Current/Power limitation of the LTM8056

    Hello,

    I have been looking into using the LTM8056 to generate 24V from a 8.5V - 34V input voltage range. I noticed in simulation that for high loads and smaller input voltages, the output power would be limited to a set value which seem independent of…

  • RE: Three LTM8056s parallel operation

    Hi Jeoffrey,

    Can LTM8056 achieve up to 4 outputs in parallel each output 4A, total 16A? 

    Regards,

  • LTM8056 minimum input @ 48V

    Hi,

    I'd like to operate the LTM8056 with an Vin ranging from 11V - 48V and output 48V @ 0.33A.  The table entry that corresponds to 48V out lists the input range from 12.5-58V.  Will the part operate down to 11V, and if so, are there any component changes…

  • ltm8056 无输出

    我使用LTM8056电源芯片,输入36V,输出40V,在无负载情况下首次加电,输出正常,接下来准备测试输入负载能力,在外部使用电子负载,配置恒定功率15W,LTM8056输出也是正常的,然后关掉8056的电,再次上电,芯片无输出,该芯片标称的功耗是5A,电压范围也很宽,目前我没有使用电流保护功能,只当做普通的DCDC 使用。

    但是不知道为什么重新加电后的8056 没有输出,电路也是按照官方电路进行设计的。

  • LTM8056 switching frequency leackage

    hello, 

    I want use LTM8056 to provide 24V/1Amax  with 12V input voltage.

    Do you have information about switching frequency leackage at the input and output .

    The output because I use the supply for RF components.

    The input because I have to respect a template…

  • LTM8056 无输出问题

    您好,我正在使用LTM8056,输入时36V,首次上电输出40V正常,然后准备测试该芯片的负载能力,使用电子负载,先调节到恒功率15W,可以看到LTM8056输出也是正常,电流电压均正常,但是断电后再重新上电,芯片无电压输出,
    芯片没有使用它的限流功能,只做普通的DCDC 用,不知道为什么加了负载后,就没有输出了。电路是参考官方设计,输出电流没有使用。

  • RE: LT8056 Warning on LTpowerCADII when Vout = Vin

    The LTM8056 can support the application you described. The LTpowerCAD tool does not seem to have the proper calculation for "iL Ripple %" when Vin~=Vout.

    The LTM8056 datasheet shows that for 24Vin to 24Vout,  the part can achieve ~4A and in 36Vin…

  • RE: LTM8055 Parallel Operation

    Hi , 

    I have the same problem but with LTM8056.

    If you have an update please let me know. We are planning to place a Load Switch if it really occurs on the board .

    Thanking you 

    With best regards and wishes
