UC3383 STEP-UP DC/DC CONVERTERS

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 co.
