I’m simulating MP2393 in MPSmart. I’m quoting datasheet excerpt for power good functionality.
“During power-up, the power good output is pulled low.
When the output voltage is higher than 92% and lower than 120% of the internal reference voltage and the soft start is finished, the power good signal is pulled high.”
In short, power good signal is pulled high when the output voltage is in a good range. And during slow start, it should be pulled low.
However, in simulation I see that it is always pulled high.
Is power good pin behavior modelled in simulation file?
