Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

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 ...

The IRU3038 synchronous pulse-width modulation (PWM) controller IC handles the termination-voltage requirements of double-data-rate (DDR) memory arrays. By ...

This solution is said to combine a PWM controller IC with the 700V and 800V CoolMOS P7 MOSFETs in a single package, designed to support isolated and non-isolated flyback topologies. According to ...

Intersil has announced the ISL6539, a dual PWM controller IC with built-in protection and monitoring in a single IC. The controller accepts an input voltage from 5V to 15V and can operate from a 3.3 ...

Today's telecom and data communication networks require efficient, high-density dc-dc solutions for converting the -48Vdc bus to low-voltage, high-current outputs. Output voltages range from 1.5Vdc to ...
