A golden power supply that will satisfy every design requirement does not exist. Size, cost, and efficiency are the driving factors for selecting a design, causing each design to be different. This ...

This article was prompted by a friend of mine asking for help on a board with an ESP32 heart. The board outputs 2.1 V instead of 3.3 V, and it doesn’t seem like incorrectly calculated feedback ...

If you are an electronic engineer or received an education in electronics that went beyond the very basics, there is a good chance that you will be familiar with the Fairchild μA723. This chip ...

There are only a limited number of switching regulators designed to generate negative output voltages. In many cases, it’s thus necessary to use a switching regulator that was actually designed for a ...

Feedback-control schemes for linear systems have been around since at least the 17 th century, regulating pressure and distance between millstones and then, famously, to control James Watt’s steam ...

Achieving an optimized board layout by successfully implementing the golden rule regarding traces. Looking at typical buck and boost regulator circuits. 1. Shown is the board of an LT8640S switching ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

DC/DC point-of-load switch mode regulator Circuit with spread spectrum frequency modulation can be designed for low EMI, write Alan Chern, Doug La Porte and Afshin Odabaee Switch mode DC/DC regulators ...

DC-to-DC switching converters are widely used in most portable devices. They efficiently generate various regulated supply voltages for different sub-blocks within the same system board. A typical ...
