Overview

www.DataSheet4U.com Rev.5.1_00 STEP-UP, FOR LCD BIAS SUPPLY, 1-CHANNEL SWITCHING REGULATOR S-8330/8331 Series The S-8330/8331 Series is a CMOS PWM-control step-up switching regulator which mainly consists of a reference voltage source, an oscillation circuit, a power MOS FET (for S-8330 Series) , and an error amplifier.

The output voltage can adjust by built-in Electric volume circuit, and equip with shutdown function.

The S-8330 Series is low current consumption because of CMOS structure , and a step-up switching regulator constructed by externally connecting only a coil, a capacitor and a diode.

Key Features
