DESCRI PT I ON

The UTC UC3383 Series are PFM step-up DC/DC switching converter.

The UTC UC3383 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 VDD pin

function (separated power and voltage detect pins).
