The TPS544C27 device is highly integrated buck converter with D-CAP+ control topology for fast transient response. All programmable parameters can be configured by the PMBus interface and stored in non-volatile memory (NVM) as the new default values to minimize the external component count. These features make the device well-designed for space-constrained applications.

The TPS544C27 device is designed to work with Intel CPUs and fits well for single-phase, low-to-mid current SVID rails in the Intel server and SoC platforms requiring VR13, VR14, or VR14.Cloud compliance.

Fault management and status reports for the overcurrent fault (OCF), VOUT overvoltage fault (OVF), undervoltage fault (UVF), and overtemperature fault are provided on the device. The TPS544C27 device provides a full set of telemetry, including output voltage, output current, and device temperature.

TPS544C27 is a lead-free device and is RoHS compliant without exemption.

USB-TO-GPIO2 — USB-TO-GPIO2 USB 介面轉接器評估模組

此 EVM 透過標準的 A 型到迷你 B 型 USB 電纜，充當主機 PC 和一個或多個目標裝置之間的介面轉接器或橋接器。USB 介面轉接器與主機 PC 之間的通訊透過 USB 進行，而 USB 介面轉接器與目標裝置之間的通訊則是透過內部積體電路 (I²C)、通用輸入和輸出 GPIO 或兩者。橋接器會轉換 USB 和 I²C/GPIO 之間的通訊交易。
