Overview
The UCC14341BQDWNRQ1 is an automotive-grade, high-density isolated DC/DC converter module manufactured by Texas Instruments. It provides a single output of 15 V to 25 V with a maximum current of 60 mA and a total power rating of 1.5 W. The device operates from an input voltage range of 13.5 V to 16.5 V and features a robust isolation voltage of 5 kVAC. Packaged in a compact SSOP-36 format measuring 12.93 mm x 7.6 mm x 3.55 mm, it supports an industrial temperature range from -40°C to +125°C.
Feature Summary
- High-density integrated transformer design for compact form factor
- Automotive qualification compliant with AEC-Q100 standards
- High isolation voltage capability for safe gate driver powering
Applications
- Powering IGBT gate drivers in automotive inverters
- Powering SiC FET gate drivers in high-voltage systems
- Isolated power supply for automotive control modules
Procurement Notes
Verify the specific suffix 'B' against the official Texas Instruments datasheet to confirm any distinct manufacturing lot or revision differences compared to the standard UCC14341QDWNRQ1 variant. Ensure the component meets the required AEC-Q100 grade for your specific automotive application environment before finalizing procurement.
Selection Notes
Select this module when driving IGBT or SiC devices requiring high isolation voltage in space-constrained automotive designs. The fixed input range suits 12V or 24V nominal systems. Consider the 1.5W power limit and 60mA output current to ensure compatibility with the target gate driver's peak and average power demands.
Part Context
This component belongs to the UCC1434x-Q1 family of isolated DC/DC converters designed specifically for automotive applications. These modules integrate the transformer to achieve high density, distinguishing them from discrete transformer solutions. They are engineered to provide reliable galvanic isolation for high-side gate drivers in electric vehicle traction inverters and other high-voltage automotive subsystems.
Replacement Considerations
The UCC14341QDWNRQ1 serves as the primary equivalent within the same product family. Verify pinout compatibility and electrical specifications against the UCC14141QDWNRQ1 if system constraints differ, though the latter may have different input/output characteristics.
