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.
|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)|
Efficiency vs. Output Current VSET = 3.3 V
*) The tab on the bottom of the package enhances thermal performance and is electrically connected to GND (substrate level). It is recommended that the tab be connected to the ground plane on the board, or otherwise be left floating.
