    Hi,

    I am hoping you can help me. I am using your LM2577 unit to convert 5v 2amps to 7.5v, to power some heated gloves I have that normally take around 7.5v and up to 2 amps. If I plug in the battery to your unit I can adjust it to 7.5v no problem. However the instant I plug in your unit to the gloves, the unit shuts off. I don’t understand why that is happening because the gloves only pull a max of 2amps. Do you have any suggestions? Thanks!

    Jon

    Hello Jon，
    Thanks for writing in.
    We have sveral kinds of LM2577, so we can’t ensure which one you are talking about.
    But according to your description, the load power should be 15W and input power is only 10W.
    Input power is not enougth,so item may shuts off. Please try to use larger power supply.
    Best regards.
