2.3.4 UCC33421-Q1

UCC33421-Q1 is an automotive qualified DC/DC power module with 5kVRMS isolation rating designed to provide efficient, isolated power to isolated circuits that require a bias supply with a well-regulated output voltage. The module integrates a transformer and DC/DC controller with a proprietary architecture to provide 1.5W (typical) of isolated power with low EMI. UCC33421-Q1 integrates protection features for increased system robustness. The module also has an enable pin, synchronization capability, wide input (3.0V to 5.5V) options, and regulated 5V or 3.3V output options with headroom.
