Analog Devices unveils ultra-low-power boost regulator
ADI's ADP5090 offers low-light power conversion and multiple power path management capability for energy harvesting systems
Analog Devices has introduced what it says is the industry's most efficient ultra-low-power boost regulator for photovoltaic and thermoelectric energy harvesting systems.
The ADP5090 ultra-low-power boost regulator represents a significant leap forward in energy harvesting technology by delivering efficient conversion of the harvested power (as low as 10 µW) with sub-µW operational losses that stores the maximum amount of energy for future operation.
Harnessing "indoor" ambient light as a viable power source has become a growing trend in wireless sensor network applications worldwide.
ADP5090 Ultra-Low-Power Boost Regulator Key Features
Optimises efficient conversion of harvested limited power down to 10 µW to 1 mW range with best in class sub-µW operation losses
Programmable maximum power point tracking with open circuit voltage sensing ensures most energy extracted from harvester
250-nA quiescent current in deep-sleep mode prolongs operation time with minimised loss of ambient energy
Integrated charge pump circuitry enables cold start at 380-mV input voltage with no energy on system node
