描述

UCC12040 is a DC/DC converter with 3-kVRMS basic 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 high efficiency and 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 (typical).

High accuracy analog input module reference design with 16-bit 1-MSPS dual simultaneous-sampling ADC
TIDA-01576 — 此参考设计可在宽输入范围内使用精密的 16 位 SAR ADC 准确测量 16 通道交流电压和电流输入。该范围涵盖了保护和测量要求(包括符合 IEC 61850-9-2 的采样要求),可简化系统设计并改善跳闸时间可重复性、性能和可靠性。此参考设计使用带有集成电源转换器的数字隔离器或使用六通道数字隔离器将交流模拟输入模块 (AIM) 与主机处理器相隔离。在最简单的配置中,仅使用五个 TI 产品即可设计出完整的 AC AIM,因此可优化系统成本和尺寸。警报功能可基于样本确定交流 AIM 故障,从而更快地检测故障。ADC 具有额外的辅助通道可用于诊断数字隔离器电源的输出,或用于为测得的模拟输入进行温度漂移补偿。
