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?
