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 ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

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 ...

The EMC2102 is an RPM-based fan controller with hardware thermal shutdown. This device is packaged in a thermally enhanced, compact, 5×5, 28-pin RoHS compliant QFN package. It employs Beta ...

Enhancing your product with speed-controlled fans can be a quick and significant upgrade — reducing noise, reducing energy use, adding system health monitoring, and providing an important ...
