板级电源系统ADM1166的电源管理应用研究

ADM1166 power management and applications of board-level power system

电源是影响电子产品可靠性和耐用度的重要指标。产品性能的提升在很大程度上依赖于电源管理技术,因此需要从系统上对电源进行综合管理。基于电源管理芯片ADM1166,研究了电源管理的基本功能,包括多电源上电时序控制、电源电压异常监控功能,并研究了电源电压在线调节功能。结合实际的应用案例,对上述功能进行了测试和验证。

Power source is an important indicator to reliability and durability of electronic products, and the improvement of product performance is heavily dependent on power source management technology. Therefore, the power source should be syntheticalty managed by the numbers. Based on power management chip ADM1166, the basic functions of the power management, including power-up sequential control of multiple power sources and power supply voltage abnormality monitoring, were researched in detail. Furthermore, the on-line adjusting function of supply voltage was researched. Combined with a practical application case, the above functions were tested and validated.
