Analog Deviceshas introduced an 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 uW) with sub-uW operational losses that stores the maximum amount of energy for future operation. Harnessing āindoorā ambient light as a viable power source has become a growing trend in wireless sensor network applications worldwide.
Ā Itoptimizes efficient conversion of harvested limited power down to 10 ĀµW ā 1-mW range with best in class sub-ĀµW 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 minimized loss of ambient energy. Integrated charge pump circuitry enables cold start at 380-mV input voltage with no energy on system node.
