SPV1050 Res and Cap Equations Help

Hi,

 

Please see schema below.

 

With this circuit the cells in series are creating ~ 0.82V in office lighting.

 

LDO2 output is only 0.5v.  This does not seem right. :-)

 

Can anyone at ST help with correct selection of R1-6 suitable for two KXOB22-12X1 in series charging a 3.7v 100mAh LiPo. One too many equations in the data sheet for me!

Voc = 630mV

Vmpp = 501mV

Many thanks.
David.
