我用了两路独立的电源.用IR2110下通道来驱动BUCK电路.今天做实验,连烧了两个IR2110.我这种用法还是有问题!请高手们帮忙解决!谢谢. 500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/23/1099708368.gif');}" onmousewheel="return imgzoom(this);">

我又按zj651020老师的用法,用了两路独立的电源.输入和输出下通道公用一组电源,输出上通道用一组电源.来驱动BUCK电路,但上通道没有脉冲输出.我的这种接法也有问题!请zj651020老师和高手们帮忙解决!谢谢.
