DescripTion
Piezoelectric Energy
Harvesting Power Supply
with 14V Minimum VIN
The LTC3588-2 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.
Anultralowquiescentcurrentundervoltagelockout(UVLO)
mode with a 16V rising threshold enables efficient energy
extraction from piezoelectric transducers with high open
circuit voltages. This energy is transferred from the input
capacitor to the output via a high efficiency synchronous
buck regulator. The 16V UVLO threshold also allows for
input to output current multiplication through the buck
regulator. The buck features a sleep state that minimizes
bothinputandoutputquiescentcurrentswhileinregulation.
Four output voltages of 3.45V, 4.1V, 4.5V and 5.0V are
pin selectable with up to 100mA of continuous output
current, and suit Li-Ion and LiFePO4 batteries as well as
supercapacitors. An input protective shunt set at 20V
provides overvoltage protection.
