The ISO774x-Q1 automotive devices are high-performance, quad-channel digital isolators with 5700VRMS (DWW package), 5000VRMS (DW package) and 3000VRMS (DBQ package) isolation ratings per UL 1577. This family of devices has reinforced insulation ratings according to VDE, CSA, TUV and CQC.

The ISO774x-Q1 devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. These devices come with enable pins which can be used to put the respective outputs in high impedance for multi-controller driving applications and to reduce power consumption. The ISO7740-Q1 device has all four channels in the same direction, the ISO7741-Q1 device has three forward and one reverse-direction channels, and the ISO7742-Q1 device has two forward and two reverse-direction channels. If the input power or signal is lost, default output is high for devices without suffix F and low for devices with suffix F. See the Device Functional Modes section for further details.

PMP23630 — 適用於 HVDC 30kW PSU 的資料中心參考設計

此參考設計為一款具備高電壓 DC (HVDC) 輸出功能的兩級高效率 30kW 電源供應器。第一級為以三相輸入來源供電的三階飛馳電容器功率因數校正 (PFC) 轉換器。透過 TMS320F28P650DK 高性能微控制器執行 PFC 控制。由於電感器中的倍頻效應,選擇了飛馳電容器拓撲結構而非更傳統的拓撲結構(例如 Vienna 整流器)。這種倍增效應可使得電感器體積更小且效率更高。PFC 後接兩個 Δ-Δ 連接的三相電感器-電感器-電容器 (LLC) 轉換器。其中一個 LLC 用於 +400V,另一個 LLC 用於 -400V。LLC 轉換器可配置為獨立電源供應器,或作為單一 800V (...)

PMP23547 — GaN 式 8kW 三相圖騰柱功率因數校正和三相 LLC 參考設計

此參考設計為高密度且高效率的 8kW 電源供應器。第一個階段是三角傳導模式 (TCM) 功率因數校正 (PFC) 轉換器,接著是連接 Δ-Δ 的三相電感器 - 電感器 - 電容器 (LLC) 轉換器。兩個功率級均採用 TI 高性能氮化鎵 (GaN) 電源開關來實現。PFC 在零電流偵測 (ZCD) 架構控制機制中採用三相圖騰柱 PFC。控制方法以可變頻率運作,且可在所有操作條件下維持零電壓切換 (ZVS)。此控制透過 TMS320F280039C 高性能微控制器和含整合式 ZCD 感測的 LMG3527R030 GaN 場效應電晶體 (FET) 來執行。轉換器的運作頻率範圍約在 70kHz (...)

PMP22650 — GaN 式 6.6-kW 雙向車載充電器參考設計

PMP22650 參考設計為 6.6-kW 雙向車載充電器。此設計採用雙相圖騰柱 PFC 與具同步整流的全橋 CLLLC 轉換器。CLLLC 利用頻率和相位調變來調節所需調節範圍內的輸出。此設計在 TMS320F28388D 微控制器中使用單一處理核心,以控制 PFC 和 CLLLC 二者。同步整流可透過與 Rogowski 線圈電流感測器相同的微控制器實作。透過使用高速 GaN 開關 (LMG3522) 可實現高密度。PFC 以 120 kHz 運作,CLLLC 則以 200 kHz 至 800 kHz 的可變頻率運作。開放訊框功率密度 3.8 kW/L 實現 96.5% (...)
