Dear All,

According to the datasheet of ADP5090, the value of MPPT ratio depends on the type of harvester and it will be 0.8 for PV and 0.5 for TEG.

But I cannot understand why the ratio should be so.

Is there any reason or equation to set the ratio such values?

Regards,

Dear sir,

Actually we studied on some kind of PV cell and get the experienced data of 0.8 ratio. In fact, you can study the PV cell in your hand and get the optimal MPPT ratio.

ADP5090 senses the OCV in around 300ms. You may also consider MPPT voltage with relation to the sensed OCV.
