S-8331 Description

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...
