How to Use a 555 Timer for PWM
Rick introduces a way to generate PWM signals with nothing more than the ubiquitous 555 timer and a few discrete components."...
PWM Fan Controllers
PWM Fan Controllers... Pins (From Top), 555 Chip In Schematic Schematic Drawing. The 555 chip is fairly old among ICs, invented in 1971 - however,...
Pulse Width Modulator, with NE555 timer-oscillator
The regulation is obtained via PWM or Pulse Width Modulation. The output pin 3 of the 555 provides square-wave with an adjustable duty-cycle...
Use a 555 timer as a switch-mode power supply - 11/14/2002 - EDN
A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to turn a 555 PWM circuit into an switch-mode power supply with only one...
PWM motor controller for DC motors and fans
This 555 timer based PWM controller features almost 0..100% pulse width... Q output of 555 is used to drive the PWM cycle, so the discharge pin is used to...
