Help debug ADP2370 (fixed 3.0V) but getting 1.6V out

Hi,

This is the schematic and just today we got our board and after soldering the buck converter(ADP2370-3.0V) I was surprised to see 1.6v across the capacitor (C1) while I was supplying clean 6.0V DC. Soldering was done in a lab with the professional. The mistakes we think could be whether the connection of the respective pins of the regulator are correct. Any help would be much appreciated. Thank you.

  • Hi everybody,

    I have exactly the same problem as aryasaro, when I connect a diode to the output voltage goes awry strongly . I have to put a diode because there is a residual voltage of 1.5V output because of my connected device. If I do not put the diode, the ADP2370 grate when it is not powered. Do you have a solution? Thank you a lot.
