The UCC28951-Q1 controller is an enhanced version of the UCC28950-Q1. It is a fully compatible drop-in replacement for the UCC28950-Q1. Refer to application note Making the Correct Choice: UCC28950-Q1 or UCC28951-Q1 to determine which controller to use.The UCC2895x-Q1 devices use advanced control of the full-bridge in addition to active control of the synchronous rectifier (SR) output stage.
ZVS operation ensured over a wide range of operating conditions, while the load current naturally tunes the switching delays of the secondary-side synchronous rectifiers(SR). This functionality maximizes overall system efficiency.

UCC28950EVM-442 — UCC28950 600W 相移全橋轉換器評估模組
UCC28950EVM-442 是 600W 相移全橋式轉換器，可將 370V 至 410V DC 輸入轉換為穩壓 12V 輸出。此轉換器的設計可將 ZVS 維持至 50% 負載。此 600W EVM 旨在展示如何透過實現 50% 至 100% 負載的 ZVS，從而將 UCC28950 控制裝置用於高效率應用。為達到此高效率， UCC28950 設計用於驅動全橋式轉換器二次側同步整流器。UCC28950 也整合突衝模式和 DCM 功能，提升無負載效率
