PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

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 ...

Linear Technology Corporation announces the LT3753, a primary side, current-mode PWM controller optimized for use in a synchronous forward converter with active clamp reset. The LT3753 operates over ...

Find a downloadable version of this story in pdf format at the end of the story. Boost power converters have been widely used for Power Factor Correction (PFC) in ac-dc conversions [1] and for power ...

Modern power delivery systems with DSPs, FPGAs and CPUs run on lower supply voltages and consume higher current. In fact, sub-1 V voltages are everywhere now. Meanwhile, intermediate bus voltages have ...
