Once upon a time (2017), I published a simple design idea for filtering and attenuating PWM DAC output ripple that I’d found very useful for over a decade. It works by passive summation of the PWM ...
A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...
How to use unfiltered PWM to drive high power loads. How to properly set the PWM duty cycle for high power loads. How to drive an incandescent lamp using PWM. Sometimes it’s necessary to drive a ...
