LM3409HV的问题

Other Parts Discussed in Thread: LM3409HV, LM3409

我现在在用自己做的lm3409HV评估板在测试,我的测试用的灯是10串10并,灯的参数是If = 3200mA,Vf = 34.0V,这种灯可以在2ms承受大电流为If电流的8倍(我想用这个实现瞬间暴闪),此时每个灯的两端电压会上升到5V以上,我现在的测试环境是48V输入,我想先试着先增加电流(从1.5A增加到3A,再到5A以上),通过调节Rsns、Roff,但是效果没有出来,希望能为我指点下,我的设计方案是否就不合理,还有我应该怎么调整其中的参数,能完成我最终的设计。谢谢
