3 Description

UCC33410-Q1 is an automotive qualified 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-Q1 features a proprietary transformer

architecture that achieves a 3kVRMS isolation rating,

while simultaneously supporting low EMI and

excellent load regulation.

The UCC33410-Q1 integrates protection features for

increased system robustness such as enable pin with

fault reporting mechanism, short circuit protection and

thermal shutdown.

The UCC33410-Q1 comes in a miniaturized, lowprofile

solution VSON (4.0mm × 5.00mm) package

with 1.00mm height and > 4.1mm creepage and

clearance
