超低温环境中LTM4616稳压电路的改进与应用

Improvement and application of LTM4616 regulated circuit in ultralow temperature environment

为了研究LTM4616电源模块在超低温环境中的抗干扰性,首先在常温条件下设计一个合理的、稳定工作的LTM4616供电电路,再将其置于-40℃超低温环境中工作。针对该电路在超低温环境中工作暴露的缺陷,改进LTM4616配置电路,并进行实验验证。结果表明,改进后的电路具有良好的常温、超低温工作性能以及较强的环境适应能力。

In order to study the anti-jamming capability of the LTM4616 power module in the ultralow temperature environment,a LTM4616 power supply circuit that operates stably in normal temperature conditions is designed and placed in the ultralow temperature environment of-40℃.In view of the defects exposed in the ultralow temperature operation of the circuit,the LTM4616 configuration circuit is improved and verified through the test.The results show that the improved circuit features favorable working performance at normal and ultralow temperature and strong environmental adaptability.
