This Design Idea describes a circuit employing a small microcontroller-based sensor module with only three connections: 5V dc, an RS-232 transmit-data output, and ground. A dedicated single-voltage ...
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 ...
For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...
The simplest of fan-control schemes an on-off switch is simple but inefficient, because it provides more cooling than necessary most of the time. When The simplest of fan-control schemes — an on-off ...
