3 Description

The UCC33420 is an industrial DC/DC power module

with integrated transformer technology designed to

provide 1.5W of isolated output power. It can support

an input voltage operation range of 4.5V to 5.5V

and regulate 5.0V output voltage with a selectable

headroom of 5.5V.

The UCC33420 features a proprietary transformer

architecture that achieves a 3kVRMS isolation rating,

while simultaneously supporting low EMI and

excellent load regulation.

The UCC33420 integrates protection features for

increased system robustness such as enable pin with

fault reporting mechanism, short circuit protection and

thermal shutdown.

The UCC33420 comes in a miniaturized, low-profile

VSON (4.00mm × 5.00mm) package with 1.00mm

height and > 4.1mm clearance and creepage.
