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 ...

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 ...

SAE Transactions, Vol. 116, SECTION 7: JOURNAL OF PASSENGER CARS: ELECTRONIC AND ELECTRICAL SYSTEMS (2007), pp. 202-210 (9 pages) PWM control is used to regulate the power supplied to automotive ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Power management leader, Kinetic Technologies, is expanding its portfolio with the introduction of KTB2140. This single-chip, highly integrated active-clamp ...

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.

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 ...

A cooling system can sometimes be a buzzkill. You drop your badass engine into your badass hot rod, and then you remember you've got to keep it cool. As an afterthought, you order a big aluminum ...
