Dear Sir,
we are encountering a LM3431 power on issue, when we power on the power supply, LM3431 output voltage will shutdown after 10ms. once we increase the capacitor value of DLY to 1uF ( from 0.1uF to 1uF) then it does work very well without any problems.
may I have your comment that the effect of DLY 0.1uF to 1uF ?
Thanks.
