Hi Team,
I have a question about LM3409 PWM dimming.
LM3409 takes longer time to start 1st switching than 2nd~ switching after EN pin becomes "High".
If we use lower PWM dimming frequency and lower duty cycle, LM3409 might recognize every switching is 1st switching so it takes long time to start switching after EN pin becomes "H".
Could you let me know the reason why 1st switching takes longer switching start time than 2nd?
Regards,
Kai
