www.DataSheet.co.kr Rev.1.2_00 ULTRA-LOW VOLTAGE OPERATION CHARGE PUMP IC FOR STEP-UP DC-DC CONVERTER STARTUP S-882Z Series The S-882Z Series is a charge pump IC for step-up DC-DC converter startup, which differs from conventional charge pump 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.
