The UCC21231 is an isolated dual-channel gate driver family with programmable dead time and wide temperature range. This device exhibits consistent performance and robustness under extreme temperature conditions. UCC21231 is designed with 4A peak-source and 6A peak-sink current to drive power MOSFET, and GaN transistors.

The UCC21231 can be configured as two low-side drivers, two high-side drivers, or a half-bridge driver. The input side is isolated from the two output drivers by a 1.6kVRMS isolation barrier, with a minimum of 125V/ns common-mode transient immunity (CMTI).

Protection features include: resistor programmable dead time, enable feature to shut down both outputs simultaneously, integrated de-glitch filter that rejects input transients shorter than 5ns, and negative voltage handling for up to –2V spikes for 200ns on input and output pins. All supplies have UVLO protection.

The UCC21231 device accepts VDD supply voltages up to 25V. An input VCCI range from 3V to 5.5V makes the driver suitable for interfacing with digital controllers. All supply voltage pins have undervoltage lock-out (UVLO) protection.

With all these advanced features, the UCC21231 device enables high efficiency, high power density, and robustness in a wide variety of power applications.

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 (...)
