dear friends,
i have a problem in DC/DC buck. please view the attached fig.
this is output of my DC/DC. it seems that there is a DC ripple, DC is not constant, but the value of riplle is very small (1~3mv). based on my privous projects the output should be very flat.
is it stable? or unstable? or some other reason?
could you give me a hint?
best regards,
