Texas Instruments TPS62170DSGR

The TPS6217x device family are easy to use synchronous step-down DC-DC converters optimized for applications with high power density. A high switching frequency of typically 2.25 MHz allows the use of small inductors and provides fast transient response as well as high output voltage accuracy by utilization of the DCS-Control™ topology.

With its wide operating input voltage range of 3 V to 17 V, the devices are ideally suited for systems powered from either a Li-Ion or other battery as well as from 12-V intermediate power rails. It supports up to 0.5-A continuous output current at output voltages between 0.9 V and 6 V (with 100% duty cycle mode).

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, 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, available in adjustable and fixed output voltage versions, is packaged in a 2-mm × 2-mm 8-pin WSON package (DSG).

家庭的tps6217x装置易于使用的同步降压DC-DC转换器具有高功率密度的应用优化。高开关频率通常为2.25 MHz允许使用小型电感器和提供快速的瞬态响应,以及由DCS控制™拓扑利用输出精度高电压。
它的宽输入电压范围为3 V至17 V,该设备非常适合于系统的动力来自Li Ion或其他电池以及12V电源轨的中间。它支持高达0.5-连续输出电流输出电压0.9 V和6 V之间(100%占空比)。
功率排序也可以通过配置启用和打开漏电源好引脚。
在省电模式下,器件具有约17µ从VIN的静态电流。省电模式,如果负载小,自动无缝地输入,在整个负载范围内保持高效率。在关机状态下,关机,关机电流消耗小于2µA.
该装置,可调整和固定输出电压版本,封装在一个2毫米×2mm引脚WSON封装(DSG)。
