Optimized for AC/DC power supplies in industrial applications, Rohm’s PWM controller ICs support a wide range of power semiconductors. Mass production has begun for four variants: the BD28C55FJ-LB for ...

iWatt has launched two digital pulse width modulation (PWM) controllers that enable smaller (as small as 2cm x 2cm x 1.7cm), greener power adapters up to 40W. iWatt has launched two digital pulse ...

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 high-speed PWM operation. Designed for ...

ELECTRONICS: Intersil Corp. introduced the industry’s most robust, military temperature, radiation-hardened PWM controllers for flyback and forward topologies. The ISL7884x family is electrically ...

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 ...

Normal fan ports are only 1 amp, so I don't typically like running more than one fan per. That's only 5 watts, after all. Normal fan ports are 12V, not 5V. A lot of 12V fans won't even start at 5V, ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...
