https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/627295/tps54360-short-circuit-fail-at-45v
我已设计 SD 电路、将10-50V 转换为5、4V 2A
在正常测试期间、当我 轻轻连接/断开 V+时、VIN=10V 至50V 工作正常
但是、在测试期间、当我尝试多次断开/连接电源的 V+时、
经过几次尝试、TPS54360出现故障、Vin (PIN2)对 GND (引脚7)短路
该故障仅在电压为45-50V 时出现、
10V 至40V 电压下没有问题
请告诉我为什么会发生这种情况？ 我应该如何防止 失败？
