LTC3588-1  
Piezoelectric Energy  
Harvesting Power Supply  
FEATURES  
DESCRIPTION  
The LTC®3588-1 integrates a low-loss full-wave bridge  
rectifier with a high efficiency buck converter to form a  
complete energy harvesting solution optimized for high  
output impedance energy sources such as piezoelectric  
transducers. An ultralow quiescent current undervoltage  
lockout(UVLO)modewithawidehysteresiswindowallows  
charge to accumulate on an input capacitor until the buck  
converter can efficiently transfer a portion of the stored  
charge to the output. In regulation, the LTC3588-1 enters  
a sleep state in which both input and output quiescent  
currents are minimal. The buck converter turns on and  
off as needed to maintain regulation.

Four output voltages, 1.8V, 2.5V, 3.3V and 3.6V, are pin  
selectablewithupto100mAofcontinuousoutputcurrent;  
however, the output capacitor may be sized to service a  
higher output current burst. An input protective shunt set  
at 20V enables greater energy storage for a given amount  
of input capacitance.
