MPM3610 5V Buck Converter

Post by Timrist »

I ordered 4 of the 5v Buck converters. (Invoice 2761469). I tested two of these using a 12v 2.5V input and the buck converter is only outputting 4.4 volts. This is not enough voltage to run the Bluetooth modules in my projects. Should I have expected the full 5v? Thank you.

Yes, you should be getting 5v. Can you post a clear closeup of the component side of the board to see if there's a visible problem.

In the meantime, please email [email protected] with a link to this thread, your order number, and request the replacement of 2 5v buck convertors matching the order.

I have tested all four and cannot get 5v. I assume the input is Vn for + voltage in and En for ground and the output voltage is measured by 5v and GND.

My power source is a 12v wall wart and I measured a steady output voltage of just over 12V.

Thanks.

. . . and En for ground
EN is pulled up by default. Connecting EN to ground disables the output.

See page 11 of the datasheet:
