R1800数据手册集成电路（IC）的特殊用途稳压器规格书PDF

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.

特点

• 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)；
• Operating Quiescent Current (IQ)：Typ.144 nA (Ta = 25°C, at no load)；
• Output Voltage Range：2.0 V to 4.5 V (Settable in 0.1 V step)；
• Output Voltage Accuracy：±3.0%；
• Minimum Starting Power：720 nW；
• Accuracy of Maximum Power Voltage：200 mV；
• Protection Features： Reverse Current Protection (VIN ≥ 2.0 V)；
• Package：DFN(PLP)2730-12；

应用 Application

• Energy harvesting module of a photovoltaic and vibration energy harvester
