UCC12050 5 kVRMS Isolated DC/DC Converter
Texas Instruments' 500 mW, high-efficiency low EMI converter is suitable for ultra-high voltage applications
Texas Instruments' UCC12050 DC/DC converter with 5 kVRMS reinforced isolation rating is designed to provide efficient, isolated power to isolated circuits that require a bias supply with 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 UCC12050 converter integrates protection features for increased system robustness. The device features an enable pin, synchronization capability, and regulated 5 V or 3.3 V output options with headroom. The UCC12050 is a low-profile, miniaturized solution offered in a wide-body SOIC package with 2.65 mm height (typical).
