UCC12040中文资料500mW、高效 3kVrms 隔离式直流/直流转换器数据手册TI规格书

描述 Description

UCC12040 is a DC/DC power module with 3-kVRMSbasic 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 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.
