描述 Description

R1800 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.

特點(diǎn)

? Providing a low operating quiescent current (IQ 144nA) and a high efficiency (approximately 90%@10 μA).

? A Control function that enables a maximum power optimizes a power supply from an energy harvester.

特性 Features

? Input Voltage Range (Maximum Rating)：2.0 V to 5.5 V (6.5V)；
