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 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.
