Product description:

This small module uses the LTC3588 piezoelectric energy collector. This small module not only can collect the piezoelectric energy, but also can collect solar energy. There is a bridge, the input can be changed into a piezoelectric element (PZ1 and PZ2), the direct input (VIN) into a DC source. The currents of the two bridges are less than 20 volts. In addition, this board can be used as a buck regulator.

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. Normally, when LTC3588 enters sleep, the static current of the input and output is very small. Buck Regulators are automatically enabled to ensure their normal operation.

Interface can selectively access the four kinds of output voltage (1.8V, 2.5V, 3.3V and 3.6V), the output current is 100mA constant current. However, the output capacitor may suddenly release a higher current. Therefore, we set the input protect splitter is a 20 volt, it can make the input capacitor to store charge more.
