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 ...

What do you do when your maximum input voltage = 90V and /or linear regulator has unreasonable power dissipation? First, here are a few specifications to digest for a 24V @ 70°C ambient application: ...

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 ...

We often use linear regulators in our designs. They are cheap and simple – you put the regulator chip itself on the board, add two capacitors, and get a voltage. Linear regulators are imperfect, of ...

Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...

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 ...

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 ...

A comprehensive understanding of switching regulator noise is important when designing a low noise switching regulator, says Leo Liu. Generally, traditional switching regulators are considered noisy ...

What is the function of a switching voltage regulator IC? A switching voltage regulator accepts a dc input voltage and converts it to a switched voltage that can extend into the MHz region. Then, it ...
