UCC34141-Q1 is an automotive qualified , reinforced isolation, high working voltage, DC/DC power module designed to provide power to SiC and IGBT isolated gate drivers. TI’s proprietary integrated transformer and advanced control architectures achieve high power density, low noise, and a low system bill of materials. This device is capable of delivering 1.5W typical output power at 85°C ambient temperature. The highly accurate dual-output voltages, easily set by resistor dividers, enables low on-resistance, fast and reliable switching for SiC/IGBT. The low-latency feedback control reduces the output capacitance for fast load transient and supports dynamic voltage programming. The wide input voltage and adjustable VIN UVLO supports both wide battery voltage of electric vehicles and regulated input rails. The device is operational from 5.5V to 20V VIN, and can withstand VIN overvoltage transients up to 28V.

The integrated protection features, fault-report Power-Good pin, and enables function increase system robustness and save external components. The SOIC package with 8.2mm creepage and clearance distance establishes high isolation capability.

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 (...)
