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. 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.
Ricoh Electronic Devices Co., Ltd. launched buck DCDC converters RP511/RP512 and a buck-boost DCDC converter RP604 with ultra-low quiescent current, and an LDO regulator RP122 with low noise and low supply current. As IoT market expands, the strong market demands such as long-time battery driving, low noise, and miniaturization are increasing for IoT terminals. Our newly released products enable to meet the demands for IoT terminals with sensors, microcomputers, and communica
