Overview: .. 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. This feature, along with its 8-Pin SSOP package and a few external ponents, makes the S-8330 Series ideal for LCD bias generators of portable equipment. For applications requiring a high output current, products used with an external transistor (S-8331 Series) are also available.
