DESCRIPTION
The
LTC
®
3105
is a high efficiency step-up DC/DC converter
that can operate from input voltages as low as 225mV. A
250mV start-up capability and integrated maximum power
point controller (MPPC) enable operation directly from low
voltage, high impedance alternative power sources such as
photovoltaic cells, TEGs (thermoelectric generators) and
fuel cells. A user programmable MPPC set point maximizes
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, I
Q
is reduced to 10µA
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.
