The small module uses Technology LTC3588's Linear piezoelectric energy collector. This module can not only collect the energy, but also to collect solar energy. There is a bridge, which can turn the input into the piezoelectric element (PZ1 and PZ2), can be directly input (VIN) into a DC source. The currents of the two bridges are all within 20 v. In addition, this board can be used as a buck regulator alone.
It has an ultra low quiescent current under voltage lockout mode, which has a large magnetic leakage window to input capacitor charge collection, and buck regulator to the accumulation of power transferred out. Generally speaking, the static current of the input and output of the input and output of the LTC3588 is small. The buck regulator is automatically enabled to ensure its normal operation.
The interface can selectively access four output voltages (1.8V, 2.5V, 3.3V, and 3.6V), and the output current is 100mA constant current. However, the output capacitor may suddenly release a higher current. Therefore, we set the input protection splitter is a 20 volt, it can make the input capacitor to store charge more.
950nA static input current (output current - normally idle)
450nA static input current (under voltage lockout mode)
2.7V-20V input range
Integrated low loss full wave bridge, the output current is up to 100mA
Output voltage can be selected for 1.8V, 2.5V, 3.3V, and 3.6V
High efficiency integrated hysteresis Buck DC / DC
Input protection branch - to achieve the 25mA of the reverse bias current, the input voltage is 20V
