R1800K Series 144 nA IQ Low Quiescent Current Buck DC/DC Converter for Energy Harvester No. EA-414-200508 OVERVIEW R1800K is a power-storing buck DC/DC converter for a photovoltaic and vibration energy harvester. A low operating quiescent current allows a harvester to be used under a low-illumination environment, and it is suitable for an equipment with low power supplied from a harvester. KEY BENEFITS ● Providing a low operating quiescent current (IQ 144 nA) and a high efficiency (approximately 90%@10 µA). ● A Control function that enables a maximum power optimizes a power supply from an energy harvester. KEY SPECIFICATIONS • Input Voltage Range: 2.0 V to 5.5 V • Output Voltage Range: 2.0 V to 4.5 V • Output Voltage Accuracy: ±3.0% • Operating Quiescent Current: Typ.
