The Energy Harvester LTC3588 PIN's and datasheet

[meral_issa]

I ordered the SparkFun Energy Harvester Breakout - LTC3588
I wanted to test it with a custom AC source, so I connected the PZ1 to the source negative, PZ2 to the source negative, D0 D1 and GND (the three adjacent PINs) to the ground, and tried to read the output voltage from the Vcc PIN. However, I only got a constant 200MV instead of 1.8V, no matter what I changed in the source.

I know my connections are incorrect, but when I tried to return to the datasheet, I found that the PINs names in the datasheet are different than the labels put on the back of the board. And the PINs order is different than that in the datasheet.

Could someone help me with with this test? what’s the correct way to connect the board and read from it? is there any tutorials on the matter? did I misread the datasheet?

@meral_issa

a custom AC source

What might that be (frequency and voltage)?

@meral_issa

PZ1 to the source negative, PZ2 to the source negative

An AC source does not have a negative output. What are the two actual connections?

@meral_issa

the PINs order is different than that in the datasheet.

Check the schematic for those details.
