空载时电源的功耗就3.5W左右了,当接入50R负载时输出端电流接近0.1A,可是通过调整负载,电流最大只能到达0.15A,接着就电压跌落,工作不正常,还得断电一断时间再运行才能返回正常状态.哦,由于手头上没有4uH的我就用了2.2mH的代替.此图参照FSD21X的.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/70/2793331223711857.gif');}" onmousewheel="return imgzoom(this);">
