Hi,
My design parameters are as follows:
Vin=5V, Vo=1.375V, Io=2A
when start up with load(the load is a CPU), no output voltage.
but when I cut off load, no load start up , output voltage have normal volt.
check Vin and Iin, it find When the input voltage is established, Iin will be built then pulled off.
the waveform as below:
Ch1= Vin, Ch4=Iin
What protection mechanism does it seem to trigger at startup?
How to solve this issue?
thanks.
