手持测试设备中,为了从系统电池获得较高的总功率,多数系统的电池电压都在7V之上。介绍一种实用的高效率DC/DC直流电源转换器TPS6211X的性能特点和应用方法,结合项目实例,分析其在手持式测试设备中为FPGA器件提供所需电压的应用设计方案。经过实践验证,该方案能显著提高系统的工作时间,达到了预期的目标。
- Abstract:
- In most hand-held testers,in order to obtain a higher total power the battery voltage system is above7V.The performance characteristics and application methods of a practical high-efficiency DC/DC power converter based on TPS6211X are introduced in this paper.Combined with examples of projects,the design applications to provide the required voltages for FPGA of hand-held tester are analyzed.The experimental results show that applications can significantly improve the system of working time and reach the desired goal.
