3 Description

UCC33410 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 4.5V to 5.5V and regulate

3.3V output voltage with a selectable headroom of

3.7V.

UCC33410 features a proprietary transformer

architecture that achieves a 3kVRMS isolation rating,

while simultaneously supporting low EMI and

excellent load regulation.

The UCC33410 integrates protection features for

increased system robustness such as enable pin with

fault reporting mechanism, short circuit protection and

thermal shutdown.

The UCC33410 comes in a miniaturized, low-profile

solution VSON (4.0mm × 5.00mm) package with

1.00mm height and > 4.1mm creepage and clearance
