The LTC3105EMS#PBF is a high efficiency step up DC to DC converter with maximum power point control in 12 pin MSOP package. This device can operate from input voltages as low as 225mV. A 250mV low 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 energy that can be extracted from any power source. Burst mode operation with proprietary self adjusting peak current optimizes converter efficiency and output voltage ripple overall operating conditions. The AUX powered 6mA LDO provides regulated rail for external microcontrollers and sensors while the main output is charging. In shutdown, IQ is reduced to 10μA and integrated thermal shutdown offers protection from overtemperature faults.
