LTC3105  400mA Step-Up DC/DC Converter
Item # 1480
LTC3105EMS

400mA Step-Up DC/DC Converter with Maximum Power Point Control and 250mV Start-Up
Package type: MSOP 12-Pin
Description:
The LTC3105 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, IQ 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.
