The AMC0381D is a precision, galvanically isolated amplifier with a high-voltage DC, high impedance input, and fixed-gain differential output. The input is designed to connect directly to a high-voltage signal source.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels. The isolation barrier is highly resistant to magnetic interference and is certified to provide reinforced isolation up to 5kVRMS (60s).

The AMC0381D outputs a differential signal proportional to the input voltage. The differential output is insensitive to ground shifts and enables routing the output signal over long distances.

The AMC0381D is available in three linear input voltage ranges: 600V, 1000V, and 1600V. With an integrated precision resistive divider, the AMC0381D achieves better than 1% accuracy over the full temperature range, including lifetime drift.

The AMC0381D is available in a 15-pin, 0.65mm pitch SSOP package. The device is fully specified over the temperature range from –40°C to +125°C.

TIDA-010957 — 15kW 至 30kW、雙向、三相帶中性線之基於 GaN 的飛馳電容器參考設計

此參考設計提供了一個設計範本，用於實現基於氮化鎵 (GaN) 的三階層、三相帶中性線飛馳電容器功率級。使用快速切換功率裝置可在同等 125kHz 頻率進行切換、減少濾波器的磁性元件尺寸，以及提升功率級的功率密度。此多階層拓撲結構允許在最高達 900V 的較高直流匯流排電壓下使用 650V 額定功率裝置。電晶體上的較低切換電壓應力減少了切換損耗，從而實現滿功率下 98.9% 的效率。
