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 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 ...

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 ...

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 ...

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 ...

Here is an example of the built circuit on a small piece of stripboard. The 2p coin gives an indication of size. I have not included the diode D1 in this example. Side view. General layout of ...

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.
