R1801K
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 n A) 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 m V step by the setting pins.
KEY SPECIFICATIONS
- Input Voltage Range: 2.3 V to 5.5 V
- Output Voltage Range: 2.3 V to 4.5 V
- Maximum Power Point Control Voltage Range
:2.7 V to 5.3 V
- Output Voltage Accuracy: ± 3.0%
- Operating Quiescent Current:
Typ. 200 n A (Ta =25°C, at no load) under condition of VIN = 4 V, VOUT = 3.0...
