LTC3588 Energy Harvester Breakout Module

product description
The distributor uses Linear Technologies LTC3588 piezoelectric energy harvester. This circuit board can not only be used to collect piezoelectric energy, but also for solar energy. Piezoelectric components (PZ1 and PZ2) have a bridge rectifier input, DC power supply has a direct current input (VIN). Both are clamped to 20V. In addition, the board can simply be used as a standalone nano-power buck regulator.

Ultra-low quiescent current under voltage lockout (UVLO) mode with wide hysteresis window allows charge to accumulate on the input capacitor until the buck converter is able to efficiently transfer a portion of the stored charge to the output. In regulation, the LTC3588 goes to sleep with minimal input and output quiescent current. The buck converter turns on and off as needed to maintain regulation.

The four output voltages (1.8V, 2.5V, 3.3V and 3.6V) are pin selectable and provide up to 100mA of continuous output current. However, the size of the output capacitor can be used to sustain higher output current bursts. The input protection shunts set to 20V provide greater energy storage for a given amount of input capacitance.
