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 ...

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 ...

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 ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude Pulse width modulation is a form of signal ...

The LT8711 is a multitopology current mode PWM controller that can easily be configured as a synchronous buck, boost, SEPIC and ZETA DC/DC converter, or as a nonsynchronous buck-boost converter. This ...

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 ...

Hello,<P>After reading a few post from <B>stickmewithneedles</B> and <B>Unobtanium</B>, I'm planning on making a thermal fan control circuit employing PWM. <P>I've no EE degree, but I love electronics ...

Infineon claims to have come up with the industry’s first 16-phase digital PWM multiphase controller which enables currents up to 1000A and higher for next ...

[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 ...

SANTA CLARA, Calif., June 1 /PRNewswire-FirstCall/ -- National Semiconductor Corporation , a world leader in power management technology, today introduced a high ...
