The question that arises in the design of a simple PWM DAC is what the low-pass filter pole frequency should be relative to the PWM frequency. This question is addressed by deriving the design ...

There comes a time in every electronic designer’s life when, whether they know it or not, they need an analog filter in their design. If you’re coming from a digital background, where everything is ...

Chinese Digital PWM modules have come down in cost over the past few months, but picking a PWM module that will help you to do what you need actually means you have to think about a host of things, ...

…which would take a pulse-width-modulated waveform at any frequency, and produce a signal with exactly the same mark/space ratio, but at a nominated frequency (see ‘Why might this be useful?’ below).

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 ...

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 ...

We love little tricks like this. Suppose that you want to generate an IR remote’s signal. It’s easy, because most of the codes are known. But it can be slightly harder because most IR remotes and ...

Precise configuration is simple with a convenient USB connection to a PC. Other features include an operating temperature range of -40 to 80 °C (32-176 ºF), electrical noise immunity, and surge ...
