I am not clear on the issue here. Can you elaborate? What is the issue?
You have FAULT and SD tied together in the schematic so if the voltage on SD is going low it is likely being pulled low by FAULT trigger. FAULT can trigger due to short circuit…

Part Number: TPS7N49 Other Parts Discussed in Thread: TPS74801 你好,ti 专家团队:
项目设计中VBIAS=5V,VIN=1.8V,EN下拉电阻到GND,实现1.8V转1.2V输出,VBIAS会先VIN稳定,EN变高在VIN=1.8V之后。
PG在什么情况下能可靠输出状态?Figure6-1上有3个输入决定,7.1.6也描述了PG需要在最小电压以上才能有效,这个电压是VBIAS吗,值是多少?
Cout的要求是>=10uf,由于MLCC有DC…
