电源管理
ADI公司Power by Linear高性能模拟IC为汽车、电信、工业、医疗、计算、军事和高端消费电子市场中的电源管理和转换应用提供高效解决方案。我们的IC提供无与伦比的功率密度和软件设计仿真工具，实现快速、精确的电源设计。
Silent Switcher®：高效率、低 EMI
电源管理工具
LTpowerPlay® 是一个强大的开发环境，支持ADI 的电源系统管理 (PSM) 产品，包括 PMBus 电源系统管理器和集成 PSM 的 DC/DC 电源转换器。该软件支持许多不同的任务，包括离线模式 (没有硬件) 以便构建一个能够保存并在日后重新载入的多芯片配置文件。
The LTpowerCAD® design tool is a complete power supply design tool program that can significantly ease the tasks of power supply design and provides recommendations for component values and performance estimates specific to the user’s application with the μModule and monolithic DC/DC regulator products of Analog Devices. This guides the user through the entire design process reducing design effort and speeding up design time.
ADIsimPE由SIMetrix/SIMPLIS驱动，是针对模拟和混合信号电路设计和开发而优化的电路仿真套件。SIMetrix模式适合用来仿真通用非开关电路。它能完全兼容Pspice，用于工业标准SPICE模型中。SIMPLIS（仿真分段线性系统）模式可仿真开关电路的工作情况，相比标准SPICE极大地改善了稳定性、速度和精度。它尤为适合开关电源、PLL和ADC/DAC应用。
