Overview
The UCC12050DVER is an automotive-qualified DC/DC power module designed by Texas Instruments. It features a 5-kV RMS reinforced isolation rating, making it suitable for providing efficient, isolated power to isolated circuits that require a well-regulated output voltage. The module integrates a transformer and DC/DC controller with a proprietary architecture, offering 500 mW of isolated power with low EMI. It is available in a 16-pin wide-body SOIC package with an extended temperature range of –40°C to 125°C, and it includes various protection features such as short circuit recovery and thermal shutdown.
