The configuration on the ST pins with the pull-up and series resistors needs to be as below for correct readings when the pin is pulled low:
Is L3076-3079 the cable resistance?
Unless you have an upstream diode for reverse battery protection, it is recommended…

Hi Ti engineer，
请帮忙检查一下LM5069电路这样设计是否合理，输入和输出用的二极管型号是B370-B3100，厂家为DIODES。MOS管型号是IRF540NSPBF，厂家为International Rectifier。附件放了电路设计的PDF文档和设计参数表格，谢谢！

Part Number: BZX884C18V
Hello TI engineer,
In my flyback power supply, the auxiliary winding voltage is rated 18V, but rises to 21V under heavy load.
I tried a series resistor（2.5ohm） + Zener diode （BZX884C18V）clamp to limit the auxiliary voltage, but…
Thank you for your reply. My usage scenario is that the tps61289 operates in boost mode, with an input of 3V and an output of 17V at a current of 5A. In this extreme case, the peak current of the built-in current-limiting MOSFET in the chip will exceed…
Part Number: BQ24072 I am currently designing a product and facing a compliance challenge. During testing, we are required to short the input and output to bypass the BQ24072, resulting in current levels that exceed the specified limits. Could you please…
您好
7.3.2 Programmable Current Limit A high-accuracy current limit allows higher reliability, which protects the power supply during short circuit or power up. Also, it can save system costs by reducing PCB traces, connector size, and the capacity of the…
Part Number: LM5060-Q1 Other Parts Discussed in Thread: LM5060 Hi TI folks,
I would like to ask if the LM5060 will auto-recover or latch off after triggering UVLO, OVP, and current limit, once the conditions return to normal?
Thanks for the schematics. I am also not 100% sure why 7V would appear but have following suspicions for which I have some suggestions for you to implement and check

I don't see any supply decaps in the schematics - At least…
