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 ...

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 ...

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, ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

Speedfan, is right not an option, as it does not support my motherboard. I don't like MSI dragon center, and I dont want to have to go to BIOS to adjust fan speed. What software is there, aside from ...
