STEP-UP SWITCHING REGULATOR

FOR LCD BIAS SUPPLY

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 components, 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.

Features

•

= 5 V,V

OUT

= 30 V)

Low current consumption :

During operation: 100

µA

(typ.) (V

= 5 V 180 kHz)

During shutdown : 1.0

µA

(max.)

•

Shutdown function: Stepping up operation is stopped ,

and Vout pin is shorted to GND while shutdown.

Input voltage range: 2.0 to 9.0 V

Soft start function: 3 msec (typ.)

Built-in CR oscillation circuit:

Oscillating frequency: 180 kHz (typ.) (A series)

Oscillating frequency: 50 kHz (typ.) (B series)

•

8-pin SSOP plastic package

8-bit built-in electric volume circuit

External transistor type is available (S-8331 Series)

Applications

•

Power supplies for medium type or large type

LCD panel.

•

Power supplies for portable devices such as

pagers, handy calculators, and remote controllers

•

Constant voltage power supplies for cameras,

video equipment, and communications equipment
