Hi sir,
My PCB-ASSY is in fail status after SMT.
My input 5V, max current 1.4A,output voltage about 5.5v.
Since this device have functions of OVP, OTP, OSP, UVL,
So I think it’s difficult for broken.
Now the fail status is input short between VIN and GND,
What’s the problem?
Why this device is broken?
Can you provide any suggestion on probability or reason?
BTW, if the input voltage is fluctuating around UVLO for a long time, is this can case failure?
Tks,
Regards,
