Ultralow Voltage Step-Up
Converter and Power Manager
The LTC3108 is a highly integrated DC/DC converter ideal
forharvestingandmanagingsurplusenergyfromextremely
low input voltage sources such as TEGs (thermoelectric
generators),thermopilesandsmallsolarcells.Thestep-up
topology operates from input voltages as low as 20mV.
The LTC3108 is functionally equivalent to the LTC3108-1
except for its unique fixed VOUT options.
Usingasmallstep-uptransformer,theLTC3108providesa
completepowermanagementsolutionforwirelesssensing
and data acquisition. The 2.2V LDO powers an external
microprocessor, while the main output is programmed to
one of four fixed voltages to power a wireless transmitter
orsensors.Thepowergoodindicatorsignalsthatthemain
output voltage is within regulation. A second output can be
enabled by the host. A storage capacitor provides power
when the input voltage source is unavailable. Extremely
low quiescent current and high efficiency design ensure
the fastest possible charge times of the output reservoir
capacitor.
The LTC3108 is available in a small, thermally enhanced
12-lead (3mm
× 4mm) DFN package and a 16-lead SSOP
package.
