3 Description
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.
