UC3383
DESCRIPTION
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).
