I have some kind of interest in electronic projects, whether hobbists or a professional ones, which are based on standard and always available sub-components. Those always available parts are also called jelly bean components, like resistors, capacitors and cheap basic parts, like op amps (including in my opinion also LM741, LM324, even TL081 and the … Continue reading Switching converters nostalgia: a brief history

Dimming LEDs (part 2/3) – Sneaky non-linear events while using the PWM technique
In the previous article we tried to analyze what is the Contrast Ratio in a LED driver and how the non-idealities are giving a boundary on the minimum allowable PWM period. That was quite worth a full article, but a big part was indeed missing. Here we will go through how the PWM period and … Continue reading Dimming LEDs (part 2/3) – Sneaky non-linear events while using the PWM technique
