我在ti官网上下了28C44的spice模型,导入LTspice后运行很慢,VDD根本达不到启动电压,仿真不了,我估计是模型设置的问题,请教下正确的模型设置,感谢!!
ps:LTspice的模型如下,请帮忙指点下!

您好,
目前Webench可提供UCC28C44的仿真,Webench仿真简便,可提供大部分所需数据。您可在UCC28C44产品页面http://www.ti.com/product/UCC28C44/description的右侧看到Webench仿真入口,点击open design进入,可选择为简体中文。如下图所示:UCC28C44DR,输入:85.0V-265.0V 输出: 12.00V @ 2.0A
谢谢!
