600 nA Low Quiescent Current Boost DC/DC Converter for Energy Harvester
R1810 Series is a boost DC/DC converter for electrical power storage devices, especially dedicated for 1 cell photovoltaic energy harvester since the start-up voltage is Typ. 0.35V.
This product can start up with only 9 µW, and applicable for charging 1 cell photovoltaic element. A system which is working under low-illuminance environment can be composed with the R1810 Series.
- Providing a low quiescent current (IQ_VOUT = Typ. 600 nA), and high efficiency (66%@ IOUT = 5 µA)
- Start up with low input energy, 9 µW (low illuminance) is possible.
- Maximum power point control function is built-in.
Consumer Input Voltage Range 0.35 V to 2.1 V (2.3 V) Operating Temperature Range -40°C to 85°C (85°C) Operating Quiescent Current Typ. 600 nA (Ta = 25°C, at no load)) Output Voltage Range 2.3 V to 4.5 V Output Voltage Accuracy ±5% (Ta = 25°C) Package WLCSP-15-P1, DFN2735-14 Start-up power 9 µW Maximum Power Point Control Voltage Setting 0.2 V to 2.1 V, in 50 mV increments
