LTC3105EDD#PBF

LINEAR TECHNOLOGY  LTC3105EDD#PBF  直流-直流开关升压稳压器, 可调, 225mV-5V输入, 1.5V-5.25V输出, 400mA输出, DFN-10

The is a 400mA step-up DC/DC Converter operates 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. An 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 overall 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 over-temperature faults.
