[原创] TI BQ25504 超低功耗能量收集电池增压转换器设计方案

TI公司的BQ25504是一款最新集成纳米智能能源收集电源管理解决方案，本方案非常适合有特殊需要的超低功耗的应用环境。该产品是专门设计来有效地获取和管理微瓦和毫瓦的电力，电力通常来自各种光伏太阳能直流源或热电动发电机。BQ25504是第一种面向产品和系统实现高效的执行转换器或充电器，例如应用在对操作功耗有严格的需求无线电传感器网络。采用BQ25504设计的DC-DC升压转换器/充电器，只需要毫瓦的电力就可以工作。本文通过总结BQ25504器件的特点，介绍器件、特性、应用方向及内部结构框图，并给参考设计实例原理图、制板图及元器件清单。

The bq25504 is the first of a new family of intelligent integrated energy harvesting Nano-Power management solutions that are well suited for meeting the special needs of ultra low power applications. The product is specifically designed to efficiently acquire and manage the microwatts (μW) to miliwatts (mW) of power generated from a variety of DC sources like photovoltaic (solar) or thermal electric generators. The bq25504 is the first device of its kind to implement a highly efficient boost converter/charger targeted toward products and systems, such as wireless sensor networks (WSN) which have stringent power and operational demands. The design of the bq25504 starts with a DCDC boost converter/charger that requires only microwatts of power to begin operating.
