  • 概述

    R1801 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.

    • 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.
    • Adjustable the output voltage and maximum power point control voltage in 100 mV step by the setting pins.
