急!急!Fly-Buck拓扑,非隔离的Primary output不接任何负载(即VDD和GND2输出的10.3V不用),那么隔离后的4路输出能正常输出吗?

Other Parts Discussed in Thread: LM5017, LM5160, LM5160A

请问各位老师:

使用LM5017Fly-Buck拓扑,非隔离的Primary output不接任何负载(即VDDGND2输出的10.3V不用),那么隔离后的4路输出能正常输出吗?如果Primary output不接任何负载,高频变压器的初级线圈好像没有回路呀,次级能正常输出吗?

另外,我的设计输出需要15WLM5017LM5160功率偏小,请推荐一款功率稍微大点的芯片,谢谢!急!急!!

急!急!
