The TPS6213XA-Q1 devices are easy-to-use synchronous step-down DC-DC converters optimized for applications with high power density. A high switching frequency of typically 2.5 MHz allows the use of small inductors and provides fast transient response as well as high output-voltage accuracy through the use of the DCS-Control™ topology.

With a wide operating input-voltage range of 3 to 17 V, the devices are ideally suited for systems powered from intermediate bus power rails. The devices support up to 3-A continuous output current at output voltages between 0.9 V and 6 V (with 100% duty cycle mode). The output-voltage startup ramp is controlled by the soft-start pin, which allows operation as either a standalone power supply or in tracking configurations. Power sequencing is also possible by configuring the enable and open-drain power-good pins.

In power save mode, the devices show quiescent current of about 17 µA from VIN. Power save mode which is entered automatically and seamlessly if the load is small, maintains high efficiency over the entire load range. In shutdown mode, the devices are turned off and shutdown current consumption is less than 2 µA. The devices are packaged in a 16-pin VQFN package measuring 3 × 3 mm (RGT).

TIDA-00271 — 適用遠端攝影機和雷達模組的 ADAS 感測器互連參考設計基板

ADAS 感測器互連電路板適用於需要將攝影機、光達或雷達模組等遠端感測器連接至中央處理 ECU 的應用。電路板支援高達 3 個同軸和 1 個 LVDS 雙絞線資料輸入，以及 3 個 FMC 纜線和 1 個電路板至電路板連接器，以做為處理 ECU 的資料輸出。  透過同軸連接器（SMB 標準）連接的攝影機或其他感測器模組，直接透過互連板的同軸纜線（同軸電纜供電）供電。由於所有 IC 皆有獨立完整電源解決方案，且板載同軸纜線供電，因此單一汽車電池或類似寬電壓供應器可直接連接至 ADAS 感測器互連電路板上的電源接頭。板載 uC 和 LIN 介面可控制和配置互連電路板，以及隨插即用操作。
