The TPS62150A-Q1 device is an easy-to-use synchronous step-down DC-DC converter 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 device is ideally suited for systems powered from intermediate bus power rails. The device supports up to 1A 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 device shows 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 device is turned off and shutdown current consumption is less than 2 µA. The device is packaged in a 16-pin VQFN package measuring 3 × 3 mm (RGT).

TIDA-00271 — 用于远程摄像头和雷达模块中的 ADAS 传感器互连参考设计板
ADAS 传感器互连板专为需要将摄像头、激光雷达或雷达模块等远程传感器连接至中央处理 ECU 的应用而设计。该板支持最多 3 个同轴数据输入和 1 个 LVDS 双绞线数据输入，并配备 3 个 FMC 电缆和 1 个板对板连接器，用于向处理 ECU 传输数据。 通过同轴电缆连接器（SMB 标准）连接的摄像头或其他传感器模块，可直接通过同轴电缆（同轴供电）从互连板获取电源。由于所有板载 IC 均采用独立的完整供电方案，并支持同轴供电，因此可将单个汽车电池或类似的宽电压电源直接连接至 ADAS 传感器互连板上的电源连接器。板载 uC 和 LIN 接口能控制和配置互连板且支持即插即用操作。
