UCC12050 is an automotive qualified DC/DC power module with 5-kVRMSreinforced
isolation rating designed to provide efficient, isolated power to isolated
circuits that require a bias supply with a well-regulated output voltage. The
device integrates a transformer and DC/DC controller with a proprietary
architecture to provide 500 mW (typical) of isolated power with low EMI.

The UCC12050 integrates protection features for increased system robustness. The
device also has an enable pin, synchronization capability, and regulated 5-V or
3.3-V output options with headroom. The UCC12050 is a low-profile, miniaturized
solution offered in a wide-body SOIC package with 2.65-mm height (typical).
