Introduction

AI Translation

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.

Features

AI Translation
  • 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.

Applications

AI Translation
  • Energy harvesting module of a photovoltaic and vibration energy harvester
