DESCRIPTION
The LTC
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.
