The ISO776x devices are high-performance, six-channel digital isolators with 5000-VRMS (DW package) and 3000-VRMS (DBQ package) isolation ratings per UL 1577. This family of devices is also certified according to VDE, CSA, TUV and CQC.

The ISO776x family of devices provides 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 logic-output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. The ISO776x family of devices is available in all possible pin configurations such that all six channels are in the same direction, or one, two, or three channels are in reverse direction while the remaining channels are in forward direction. If the input power or signal is lost, the 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.

Used in conjunction with isolated power supplies, this family of devices helps prevent noise currents on data buses, such as RS-485, RS-232, and CAN , or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO776x family of devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO776x family of devices is available in 16-pin SOIC and SSOP packages.

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 (...)
