Hello,
I'm making step down converter (based on "Great scotts" BMS, schematic below) for LiPo battery to replace 2 AAA batteries and my knowledge about inductors is a bit weak, so I need help.
MT3420 data sheet recommends 1-4.7uH with low DCR for higher efficiency, lowest DCR I managed to find is 4.2 mOhms@2.2uH(13x13x7 mm), but also I found 24mOhms@4.7uH(8x8x4mm). How much of an impact inductor inductance and DCR has in this particular case, load will be wireless mouse (will make separate thread on it in a few min...).
Thanks in advance.
(don't mind resistors values)
