Ricoh launches Buck DC/DC Converter with 144 nA quiescent current for Energy Harvesting applications
As soon as there is sufficient energy available on the input side, the buck DC/DC Converter will be enabled to transfer energy from input to output. During this phase the transferred energy is stored in a super capacitor or battery on the output until the energy left on the input drops below a threshold. The DC/DC Converter is disabled and new energy will be collected on the input. This process repeats and increases the energy level in the capacitor or battery until the required output voltage is reached.
A reverse current protection circuit prevents that a current flow will occur from output to input as soon the energy harvesting cell does not provide energy, the circuit is triggered when the input voltage drops below the output voltage.
The R1800 is available in a DFN(PLP)2730-12 package.
