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).
FEAT URES
