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 ,

S-8330 Features

* Maximum output voltage: 20 V to 30 V (2 V step) 12 V range can be adjusted by electric volume

* Output voltage accuracy :±2.4%

* Output current: 5 mA ( VIN= 5 V,VOUT= 30 V)

* Low current consumption : During operation: 100 μA (typ.) (VIN= 5 V 180 kHz) During shutdow
