UNISONIC TECHNOLOGIES CO., LTD

L3383

CMOS IC

PFM CONTROLLED, STEP-UP

DC/DC CONVERTERS

(VARIABLE DUTY RATIO)

SOT-25

DESCRIPTION

The UTC L3383 Series are PFM step-up DC/DC switching

converter. The UTC L3383 can support both large and small

currents. It automatically switches duty ratio (45%/75%) when it

senses changes in load.

Both built-in and external transistor types include 5-pin and 3-pin

packages, which are provided with either a CE (chip enable) function

that reduces power consumption during shut-down mode, or a V_DD

pin function (separated power and voltage detect pins).

SOT-89

FEATURES

*Pb-free plating product number: L3383L

* Output voltage range: 2.0V~7.0V in 0.1V increments

* Operating (start-up) voltage range: 0.9V~10V

* Highly accurate: Set-up voltage ±2.5%

* Maximum oscillator frequency (Max Fosc1): 180kHz (±15%)

* Variable Duty Ratio: 45%/75% (±5%)

* Both switching transistor built-in and external types are available

* 5-lead package offer Chip Enable or independent V_OUTpin option.
