In previous posts, I have introduced several do-it-yourself pwm controller circuits and reviewed several Chinese PWM controller modules. The next step in this post is to share the design of another ...

Simple linear and switching voltage regulators with feedback networks of the type shown in Figure 1 are legion. Their output voltages are the reference voltage at the feedback (FB) pin multiplied by 1 ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...
