Part Number:TPS54540
We got circuit information and waveforms using with TPS54540 from customer.
When they use this IC at 2Mhz switching.There is a period that continue to Switch ON.Please see attached.
So Vout continue to increase. They would like to know why this phenomenon was seen.
If they changed diode from SM560C to SM540C,this phenomenon wasn't seen.
Please advise us. (Please visit the site to view this file)
