    Hi

    I am busy repairing a Garmin Echo 101 device that has a blown IC.

    The only information on the IC is IV7DF. (See attached foto)

    I am not able to find this component or any replacement.

    Are you perhaps able to assist me to identify the component or a possible replacement?

    Regards


    Spidey

    According to this website (Russian) it is an MP2451 step-down converter. But I don't see the required inductor.
    So maybe it is not but a linear regulator R1111N281A as suggested in a reply on the same website?

    IV7DF was listed on AliExpress and the picture is identical but says it's no longer available.
