R1801K Series Buck DC/DC Converter for Energy Harvester with Adjustable Maximum Power Point Control, Adjustable Output Voltage and PG Function OVERVIEW No. EA-422-201210 R1801K is a power-storing buck DC/DC converter for a photovoltaic and vibration energy harvester. The Power Good (PG) function can output PG signal according to the output voltage facilitating to build a system. 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 power supply (IQ 200 nA) and a high efficiency (approximately 80%@10 µA). ● Monitoring the output voltage to output Power Good (PG) signal.
