TI推出超低功率转换器 加速智能家居能量采集

TI最新推出了行业的最低功率DC / DC降压转换器,增加了采集能量。这个超低功率电路电池使用的应用程序是,如无线传感器网络、监控系统、烟雾探测器,穿戴式医疗设备和移动配件。

TI的高级副总裁,Sami Kiriaki说：想象一下如果没有烟探测器的电池，你会怎样？TI将继续研发低操作电流及高功率效率的
电路，可以提取环境能量。这个新电源电路给设计师不同于传统电池驱动的系统的设计。

Lowest power DC/DC converter

TI's TPS62736 DC/DC converter delivers high power conversion efficiency from 10 uA to 50 mA output currents,and consumes only 350 nA of active current and 20 nA during standby. The converter achieves greater than 90-percent efficiency across output currents higher than 15 uA. The TPS62736 regulator steps down the voltage from a power source, such as a thin-film or regular battery or a super capacitor and features a programmable output voltage.

Enabling energy harvesting design

Innovative power management, sensors and microcontrollers from TI are taking low-power design to the next level by optimizing extracted energy from ambient sources using the highest possible efficiency and lowest power consumption. In 2011, TI introduced its bq25504 boost charger circuit with a low quiescent current of 330nA, to allow start-up from single-cell solar cells under low light or thermoelectric generators with low temperature differences.  

TI also recently announced sampling of its MSP430FR59xx microcontrollers based on its "Wolverine" technology platform. These new FRAM-based microcontrollers can operate as low as 360 nA in real-time clock mode or less than 100 uA/MHz in active power consumption, and feature fast wakeup time of 6.5 us and high-precision peripherals. The MSP430FR59xx enable developers to add flexibility, performance and battery life to a variety of applications, including wireless sensing, energy harvesting, smart grid, building automation and security.
