DESCRIPTION
400mA Step-Up DC/DC
Converter with Maximum Power
Point Control and 250mV Start-Up
TheLTC3105isahighefficiencystep-upDC/DCconverter
that can operate from input voltages as low as 225mV. A
250mVstart-upcapabilityandintegratedmaximumpower
pointcontroller(MPPC)enableoperationdirectlyfromlow

photovoltaic cells, TEGs (thermoelectric generators) and
fuelcells.AuserprogrammableMPPCsetpointmaximizes
the energy that can be extracted from any power source.
Burst Mode operation, with a proprietary self adjusting
peak current, optimizes converter efficiency and output
voltage ripple over all operating conditions.
The AUX powered 6mA LDO provides a regulated rail for
external microcontrollers and sensors while the main
output is charging. In shutdown, IQ is reduced to 10A
and integrated thermal shutdown offers protection from
overtemperature faults. The LTC3105 is offered in 10-lead
3mm × 3mm × 0.75mm DFN and 12-lead MSOP packages.
