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
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 (V
IN
= 5 V,V
OUT
= 30 V)
Low current consumption :
During operation: 100
μA
(typ.) (V
IN
= 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
Built-in CR oscillation circuit:
Oscillating frequency: 180 kHz (typ.) (A series)
Oscillating frequency: 50 kHz (typ.) (B series)
8-bit built-in electric volume circuit
External transistor type is available (S-8331 Series)
