Texas Instruments UCC33410/UCC33410-Q1 DC-DC Power Modules

Texas Instruments UCC33410/UCC33410-Q1 Industrial DC-DC Power Modules feature integrated transformer technology, delivering 1.0W of isolated output power. It can support an input voltage range of 4.5V to 5.5V and regulate a 3.3V output voltage with a selectable headroom of 3.7V.

The UCC33410/UCC33410-Q1 features a proprietary transformer architecture that achieves a 3kVRMS isolation withstand voltage, while simultaneously supporting low electromagnetic interference (EMI) and excellent load regulation. The UCC33410/UCC33410-Q1 integrates protection features to enhance system robustness, including an enable pin with fault reporting, short-circuit protection, and thermal shutdown.

The UCC33410/UCC33410-Q1 comes in a miniaturized, low-profile VSON (4.00mm × 5.00mm) package with a height of 1.00mm and >4.1mm clearance and creepage. The Texas Instruments UCC33410-Q1 devices are AEC-Q100 qualified for automotive applications.
