Pulse Width Modulators using LM339

Posted on Feb 6, 2014

The first example uses the standard op-amp oscillator circuit to generate a triangular waveform which is level-shifted and fed to a comparator (e. g. LM339) to give the PWM waveform. Most people will want to use two comparators rather than one op-amp and one comparator so that is what we show here. Disclaimer All files are found using legitimate se
