... ICs, in that it uses fully depleted SOI (Silicon on Insulator) technology to enable ultra-low voltage operation. Being capable of stepping up an extremely low input voltage of 0.3 to 0.35 V, this series enables the efficient use of very low energy levels. The stepped up electric power is stored in a startup capacitor, and it is discharged as the startup power of the step-up DC-DC converter when the startup capacitor reaches the discharge start voltage level ...

... Operation 1. Basic Operation : IC with 2.0 V Discharge Start Voltage (1) In the S-882Z Series, when power of 0 higher is input to the VIN pin, the oscillation circuit starts operation with that power, and the CLK signal is output from the oscillation circuit. (2) The charge pump circuit is driven by this CLK signal, and the power of the VIN pin is converted to the stepped up electric power in the charge pump circuit ...
