3 Description
UCC12041-Q1 is an automotive qualified DC/DC
power module with 3-kV
RMS
basic 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 UCC12041-Q1 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
UCC12041-Q1 is a low-profile, miniaturized solution
offered in a wide-body SOIC package with 2.65-mm
height (typical).
