3 Description

UCC33020-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

3.0V to 5.5V and regulate 5.0V output voltage with a

selectable headroom of 5.5V.

UCC33020-Q1 features a proprietary transformer

architecture that achieves a 3kVRMS isolation rating,

while simultaneously supporting low EMI and

excellent load regulation.

The UCC33020-Q1 integrates protection features for

increased system robustness such as enable pin with

fault reporting mechanism, short circuit protection and

thermal shutdown.

The UCC33020-Q1 comes in a miniaturized, lowprofile

VSON (4.0mm × 5.00mm) package with

1.00mm height and > 4.1mm clearance and

creepage.
