The TPS54KC23 device is a small, high-efficiency, synchronous buck converter with an adaptive on-time D-CAP4 control mode. The control method provides low minimum on-time and fast load-transient response across the entire output voltage range without requiring an external compensation network. Because external compensation is not required, the device is easy to use and requires few external components. The device is well-designed for space-constrained data center applications.
The TPS54KC23 device has differential remote sense, high-performance integrated MOSFETs, and an accurate ±0.5% reference over the specified operating junction temperature range. The device features accurate load regulation and line regulation, Eco-mode or FCCM operation, programmable settings through the MSEL pin and programmable soft start.
The TPS54KC23 device is a lead-free device. The device is RoHS compliant without exemption.

TPS54KC23EVM — TPS54KC23 評估模組
TPS54KC23EVM 是一款適用於 TPS54KC23 產品的評估模組，TPS54KC23 為 4V 至 16V 輸入、30A 遠端感測同步降壓轉換器。此轉換器使用 D-CAP4 控制模式以獲得快速暫態回應，並透過降低對輸出電壓位準性能的依賴程度，來提升易用性。TPS54KC23 可提供兼具高 VOUT 和低 VOUT 的優異暫態回應，且無需為了實現最佳的高 VOUT 或低 VOUT 而變更應用電路圖。TPS54KC23 提供最佳化的針腳配置，以實現效率與熱性能。對稱輸入架構 (封裝兩側均具有 VIN 和 PGND 針腳) 可提供穩健的 EMI 性能。
此評估模組包含兩個階段。第一個設計 (...)
