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 ...

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 ...

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 high-speed PWM operation. Designed for ...

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 ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...
