TYPICAL APPLICATION
DESCRIPTION
Nanopower Energy
Harvesting Power Supply
with 14V Minimum V
IN
The LT C
®
3588-2 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,
solar, or magnetic transducers.
An ultralow quiescent current undervoltage lockout (UVLO)
mode with a 16V rising threshold enables efficient energy
extraction from sources 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 both input and
output quiescent currents while in regulation.
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 LiFePO
4
batteries as well as
supercapacitors. An input protective shunt set at 20V
provides overvoltage protection.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC3588E-2 is tested under pulsed load conditions such
that T
J
≈ T
A
. The LTC3588E-2 is guaranteed to meet specifications
from 0°C to 85°C junction temperature. Specifications over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC3588I-2 is guaranteed over the –40°C to 125°C operating junction
temperature range. Note that the maximum ambient temperature
consistent with these specifications is determined by specific operating
conditions in conjunction with board layout, the rated package thermal
impedance and other environmental factors.
Note 3: The junction temperature (T
J
, in °C) is calculated from the ambient
temperature
(T
A
, in °C) and power dissipation (P
D
, in Watts) according
to the formula: T
J
= T
A
+ (P
D
• θ
JA
), where θ
JA
(in °C/W) is the package
thermal impedance.
Note 4: Dynamic supply current is higher due to gate charge being
delivered at the switching frequency.
