The LTC®3588-1 integrates a low-loss full-wave bridge rectifi er with a high effi ciency 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） mode with a wide hysteresis window allows charge to accumulate on an input capacitor until the buck converter can effi ciently 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 selectable with up to 100mA of continuous output current; 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.
