UC3383 Datasheet STEP-UP DC/DC CONVERTERS

Manufacturer: Unisonic Technologies

Datasheet Details

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.
