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 ...

Designers of notebooks and other battery-powered applications on the hunt for ways to simplify design, reduce component count, and lower overall cost should look at a novel pulse-width-modulated (PWM) ...

FAIRCHILD SEMICONDUCTOR has developed the FAN302HL PWM controller for low standby power charger applications. Incorporating mWSaver™technology, the device features patented technologies that allow the ...

This DC power supply controller is controlled by pulse width modulation PWM, generated by the circuit around timer IC2 7555 according to the formula: Duty cycle = ((R1 + (VR1/2)/(R1+R2+VR1)) x 100% ...

Optimised performance, efficiency, and reliability in high-voltage power supplies need to be combined with reduced BOM count and cost, as well as lower design efforts. The FF CoolSET solution combines ...

Texas Instruments has introduced a pair of closely-related dual-output PWM dc-dc converter controllers for space applications, one radiation-hardened and the other radiation tolerant. Both can operate ...
