The LTC3108 is designed to use a small external step-up
transformer to create an ultralow input voltage step-up
DC/DC converter and power manager. It is ideally suited
for low power wireless sensors and other applications in
whichsurplusenergyharvestingisusedtogeneratesystem
power because traditional battery power is inconvenient
or impractical.
The LTC3108 is designed to manage the charging and
regulation of multiple outputs in a system in which the
average power draw is very low, but there may be periodic
pulses of higher load current required. This is typical of
wireless sensor applications, where the quiescent power
draw is extremely low most of the time, except for transmit
bursts when circuitry is powered up to make measure-
ments and transmit data.
The LTC3108 can also be used to trickle charge a standard
capacitor, supercapacitor or rechargeable battery, using
energy harvested from a Peltier or photovoltaic cell.
