S-8880A Series .ablicinc. © ABLIC Inc., 2017 ENERGY HARVESTING POWERED BY ULTRA-LOW POWER AND ULTRA-LOW VOLTAGE OPERATION BOOST CHARGE PUMP FOR STEP-UP DC-DC CONVERTER STARTUP Rev.1.0_02 The S-8880A Series is a boost charge pump for step-up DC-DC converter startup, which enables operation with ultra-low power and ultra-low voltage. An original circuit system and SOI technology allow this product to boost the industry's lowest level- 1 0.35 V ultra-low input voltage as a boost charge pump, and achieve operation with an extremely weak power of 26 W. The boosted electric power is stored in an external 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 (VCPOUT1). A built-in power-off function is also provided, so that when the output voltage of the connected step-up DC-DC converter rises above a given value, the operation is stopped, thereby achieving significant power...
