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.

TIDA-01576 — 具有 16 位元 1-MSPS 雙同步取樣 ADC 的高準確度類比輸入模組參考設計

此參考設計在廣泛輸入範圍內，使用精密 16 位元 SAR ADC 準確測量 16 通道 AC 電壓及電流輸入。此範圍涵蓋保護與測量要求 (包括 IEC 61850-9-2 的取樣要求)，可簡化系統設計並提升跳脫時間重複性、性能與可靠性。AC 類比輸入模組 (AIM) 使用具有整合電源轉換器或採用六通道的數位隔離器，與主機處理器隔離。在最簡單的配置中，完整的 AC AIM 只需使用五種 TI 產品即可設計，進而實現系統成本與尺寸最佳化。警報功能會以取樣方式識別 AC AIM 故障，以加快故障偵測速度。ADC 具有額外的輔助通道，可診斷數位隔離器電源的輸出，或補償量測類比輸入的溫度漂移。
