Hello! I am building a 50-600Vin flyback converter using the altair04-900 to power an LED as a student project. Due to the very light load I expect it to work in Burst mode. Currently I am looking for an adequate transformer. On this regards my question; which switching frequency should I expect? The datasheet talks about 2-8kHz around burst mode threshhold. Does someone have any experiences with the operation of this IC in burst mode?
