LTC3105 Datasheet 400ma Step-up DC/dc Converter

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC3105 400mA Step-Up DC/DC Converter with Maximum Power Point Control and 250mV.

General 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.
