About the harvester of ADP5091

您好:Kevin.Yao@

1、我注意到datasheet第一页上“The ADP5091/ADP5092 provide efficient conversion of the harvested limited power from a 6 μW to 600 mW range with submicrowatt operation losses. ”5091可以从PV获得的最大功率就是600mW吗,或者更高?

2、请问如果我有一个太阳能电池,它的开路电压是5V,最大短路电流是150mA。我可以连接它和ADP5091吗,如果可以,Vmppt 是不是应该设置为最大功率点的电压,mppt=0. 7-0.85吗     

3、如果问题2的PV不可以连接到5091,是因为输入电压最大为3.3V吗?输入电压的限制是PV的开路电压还是Vmppt?

 

1. I noticed on the first page of the datasheet that “The ADP5091/ADP5092 provides efficient
conversion of the harvested limited power from a 6 μW to 600 mW range with submicrowatt
operation losses.” 5091 Can the maximum power obtained from the PV be 600 mW, or higher? 
2. if I have a solar cell, its open circuit voltage is 5V, the maximum short-circuit
current is 150mA. Can I connect it to the ADP5091? If yes, should Vmppt be set to the
maximum power point voltage, mppt=0. 7-0.85? 
3. If the problem 2 PV cannot be connected to the 5091, is the input voltage maximum 3.3V?
Is the input voltage limit the open circuit voltage of PV or Vmppt?
