3 Description
UCC12040 is a DC/DC converter with 3-kVRMS basic
isolation rating designed to provide efficient, isolated
power to isolated circuits that require a bias supply
with a well-regulated output voltages. The device
integrates a transformer and DC/DC controller with a
proprietary architecture to provide 500 mW (typical) of
isolated power with high efficiency and low EMI.
The UCC12040 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
UCC12040 is a low-profile, miniaturized solution
offered in a wide-body SOIC package with 2.65-mm
height (typical).
