UCC12051-Q1数据手册TI中文资料规格书

描述 Description

UCC12051-Q1 is an automotive qualified DC/DC power module with 5-kVRMS 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 UCC12051-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 UCC12051-Q1 is a low-profile, miniaturized solution offered in a wide-body SOIC package with 2.65-mm height (typical).
