Texas Instruments UCC33410 1W Isolated DC/DC Modules

Texas Instruments UCC33410 1W Isolated DC/DC Modules feature integrated transformer technology and are engineered to provide 1W of isolated output power. These DC/DC power modules support a 4.5V to 5.5V input voltage operation range and regulate 3.3V output voltage with a selectable headroom of 3.7V. The UCC33410 series uses a proprietary transformer architecture that achieves a 3kVRMS isolation rating while supporting excellent load regulation and low electromagnetic interference (EMI). The integrated protection features provide increased system robustness and include thermal shutdown, short-circuit protection, and an enable pin with a fault reporting mechanism. The UCC33410-Q1 variant is AEC-Q100 qualified and functional safety-capable. Texas Instruments UCC33410 1W Isolated DC/DC Modules offer a miniaturized VSON 4mm x 5mm package with a low 1mm height and >4.1mm creepage and clearance.
