The UCC33020 is an industrial DC/DC power module with integrated transformer technology designed to provide 1.0W of isolated output power. It can support an input voltage operation range of 3.0V to 5.5V and regulate 5.0V output voltage with a selectable headroom of 5.5V.

The UCC33020 features a proprietary transformer architecture that achieves a 3kVRMS isolation rating, while simultaneously supporting low EMI and excellent load regulation.

The UCC33020 integrates protection features for increased system robustness such as enable pin with fault reporting mechanism, short circuit protection and thermal shutdown.

The UCC33020 comes in a miniaturized, low-profile VSON (4.0mm × 5.00mm) package with 1.00mm height and > 4.1mm clearance and creepage.
