I'm prototyping an energy harvester (solar and vibration) for low voltage applications and I thought about the LTC3330 / LTC3331 ICs.
My question is about the minum input voltage fro the ICs to work.
1) First we have the diode bridges wiht a voltage drop of 800mV
2) Then the energy transfer from in put cap to output cap starts when then Vin voltage is > UVLO [4V]
Adding 1 and 2 this is 4.8V
Is it true that there will be no energy harvest until the harvest voltage > 4.8V ??
