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 ...

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 ...

Linear Technology Corp.’s new LTC3723 push-pull synchronous PWM controller is specifically targeted toward compact and highly efficient isolated power supplies. The LTC3723 controller's basic features ...

Proper thermal dissipation is an essential rule for nowadays electronics. The best operating temperature for the electronic components is 25 degrees (standard room temperature). Thermal dissipation in ...

Normal fan ports are only 1 amp, so I don't typically like running more than one fan per. That's only 5 watts, after all. Normal fan ports are 12V, not 5V. A lot of 12V fans won't even start at 5V, ...

Toshiba has launched two sine-wave pulse width modulated (PWM) drive controllers – TC78B043FNG and TC78B043FTG – for three-phase brushless DC (BLDC) motors, which can support both surface permanent ...
