Well, I have a lipoly single cell and ixolar solar cell from iXys (Vmpp = 4.3v) connect to the spv1050.Buck boost not working correctly, efficiently is worst bad. (I got onlt a fraction of Amp from a direct connection to my battery!)it is impossible ...

I use a solar panel ref SM141k08l from IXOLAR and the sp1050 schematic from eval board ISV020V1 in a buck boost version. Just change some resistor to adjust Vppm to 4.8v (I got it in my test, but only 15mA is push to my Lipo battery, lipo voltage is ...

My god an answer! Many thanks Jostikas!EOC voltage is at 4.5v and battery is a single lipo.my solar cell best power output is around 40mA..So with your explanation I understand why it's not working...But this is not clearly visible when you look to d...

It appeared that nobody answer on spv1050 questions.. I had same problem as ask before : could not activate ldo if there are no charge ! even if battery is full! This is crazy! Also boost buck not working as expected.

SPV1050 very bad efficiency with solar panel. In same condition charge current is 15mA with spv1050 and 50mA with battery directly connect to solar panel. Help need
