The TPS6208x devices are a family of high frequency synchronous step down converters. With an input voltage range of 2.3 V to 6 V, common battery technologies are supported. Alternatively, the device can be used for low voltage system power rails.

The TPS6208x focuses on high efficiency step-down conversion over a wide output current range. At medium to heavy loads, the converter operates in PWM mode and automatically enters Power Save Mode operation at light load currents to maintain high efficiency over the entire load current range. To maintain high efficiency at very low load or no load currents, a Snooze Mode with an ultra-low quiescent current is implemented. This function, enabled by the MODE pin, increases the run-time of battery driven applications and keeps the standby current at its lowest level to meet green energy standards targeting a low stand-by current.

To address the requirements of system power rails, the internal loop compensation allows a large selection of external output capacitor values in excess of 100 µF. With its DCS-Control™ architecture, excellent load transient performance and output voltage regulation accuracy is achieved. The device is available in 2-mm × 2-mm WSON package with Thermal PAD.

TIDM-MINI-DC — 適用於較小型 AMI 網路、可降低基礎設施成本的資料集中器參考設計

TIDM-MINI-DC 參考設計實作了一個輕量型電力線通訊 (PLC) 資料集中器 (DC) 解決方案，並整合了乙太網路中繼器功能。電力網路是靜態的，這表示一旦終端節點安裝完成，DC 所需支援的節點數量即為固定。電力公司經常擁有許多饋電線路，但每條線路上僅有少數終端消費者。對這些線路而言，安裝一套可支援大量終端節點的高性能 DC 解決方案並不具成本效益。本設計提供一個低成本的 PLC DC 解決方案，支援較小規模的網路，並具備乙太網路中繼器（或邊緣路由器）功能，將本地 PLC 網路與乙太網路主幹網路互連，讓控制中心能直接控制 PLC 終端節點。
