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

26

μW.

The boosted electric power is stored in an external startup capacitor, and it is discharged as the startup power of the step-up

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 saving and contributing to lower power consumption of devices.

It also includes boost flying capacitors, which allows for formation of a step-up DC-DC converter startup circuit by adding a

minimum of just one external capacitor, thus realizing miniaturization of devices.
