Part Number:TPS51285A
Hi expert,
Customer has a question on CCM --> DEM. Below is the waveform that TPS51285A cannot get into DEM mode, we think it is due to wide ZCD threshold.(inductor current is down to -15.6A but it is still in CCM) Would you kindly help to check if it is normal operation for TPS51285A? Thanks a lot!!
Best regards,
Ann Lien
