最近在设计实例专栏中，人们对一系列以脉冲宽度调制(PWM)控制通用型稳压器(包括线性稳压器和开关稳压器)的简易接口电路产生了浓厚兴趣。这类电路的共通点，是利用稳压器内部的电压参考源，并在稳压器的设定电压分压电阻串联一个分立的FET。jyFednc PWM通过 ...

I recently published a Design Idea (DI) showing some very simple circuits for PWM programming of standard regulator chips, both linear and switching, “Revisited: Three discretes suffice to interface ...

I’ve recently published Design Ideas (DIs) showing circuits for linear PWM programming of standard bucking-type regulators in applications requiring an output span that can swing below the regulator’s ...
