TI UCC12041QDVERQ1

The UCC12041-Q1 is an automotive-grade DC/DC power module with a 3kVRMS basic isolation rating. It is designed to provide an effective isolated power supply for isolated circuits that require a bias power supply and regulated output voltage. This device integrates a transformer with a proprietary architecture and a DC/DC controller, which can provide 500mW (typical) of isolated power and has low EMI. The UCC12041-Q1 integrates protection features to enhance system robustness. The device also features an enable pin, synchronization function, and options for 5V or 3.3V regulated outputs (with headroom voltage). The UCC12041-Q1 is a thin and miniaturized solution, packaged in a wide-body SOIC package with a height of 2.65mm (typical).
