However, Proteus does not include the LM2596 in its default libraries. Searching for "lm2596 proteus library download free top" often leads to broken links, malware-ridden ZIP files, or outdated models.
Proteus 的原生库主要用于教学，主要包含 555 定时器、74 系列逻辑门等基础元件，对现代大功率电源芯片的覆盖并不全，尤其是在开关电源设计领域。当你需要一个能处理 、输入电压高达 40V 的 DC-DC 芯片 LM2596 时，官方库就会显示“No results found”。
