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 ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

A pulse width modulator (PWM) controller from Microchip Technology allows the introduction of digital control into analog power-supply designs while providing A pulse width modulator (PWM) controller ...

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 ...

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 ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Since the early 1990s, the power requirements for VCC core voltages for leading-edge processors and ASICs have become increasingly demanding, with chip voltage decreasing and current increasing. Early ...

This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

With a 4k1 collector resistor and 16mA drive into the led, the chosen (read ‘cheapest on ebay’) 6N135 is supposed to beat 1.5μs for both turn on and turn off, with typical figures of 90ns and 800ns.
