DESCRIPTION
Demonstration Circuit 1459B is an energy harvesting
power supply featuring the LTC3588-1/LTC3588-2.
The LTC3588 integrates a low-loss full-wave bridge
with a high efficiency buck converter to form a com-
plete energy harvesting solution optimized for high
output impedance energy sources such as piezoelec-
tric transducers. An ultralow quiescent current under-
voltage lockout mode with a wide hysteresis window
allows charge to accumulate on an input capacitor
until the buck converter can efficiently transfer a por-
tion of the stored charge to the output. Four output
voltages are pin selectable with up to 100mA of con-
tinuous output current. A power good comparator

produces a logic high referenced to VOUT on the
PGOOD pin when the converter reaches the pro-
grammed VOUT, signaling that the output is in regula-
tion.
The LTC3588EMSE-1/LTC3588EMSE-2 are available
in a 10-lead (3mm × 3mm) MSE surface mount pack-
age with exposed pad.
