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 you plug almost any small computing or consumer electronics device into a power receptacle, it's safe to say that the plug you are holding links to an external power supply (EPS). This is crucial ...

This PWM Controller circuit is ideal for controlling small motors with 2A maximum current consumption. For higher currents you need additional cooling for T2 and increase C2 value. This pwm motor ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

High current PWM controller announcements include an 80A device from International Rectifier and a 60A chip from TI. IR’s 80A programmable two-phase interleaved pulse width modulation (PWM) controller ...

So my PC was noisy and I invested in 120mm Akasa Apache fans. Now I have 4 Apache fans (2 on the CPU cooler), 1 sucking the air out at the back and to balance the pressure, one Apache blowing cold air ...

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 ...

FAIRCHILD SEMICONDUCTOR has developed the FAN302HL PWM controller for low standby power charger applications. Incorporating mWSaver™technology, the device features patented technologies that allow the ...

This solution is said to combine a PWM controller IC with the 700V and 800V CoolMOS P7 MOSFETs in a single package, designed to support isolated and non-isolated flyback topologies. According to ...

[hedgehoginventions] wrote in to share a little modification he made to his video card in order to keep it from overheating during strenuous 3D tasks. Having swapped out the stock cooler on his Nvidia ...
