I designed flyback power supply 65v/3amps using Topswitch262EN . I got the output 65v stable . when i put the load 1amp it is ok but when i increase the load 2amps the output is going off that is thermal shutdown. i got the drain to source wave form .i am not understanding the wave form is it ok or not please tell me that drain to source wave form are ok or not and also tell me ic is not supporting 3amps . i will attach the waveforms and implemented board.
