Switching regulators have delivered such convenience and efficiency compared to their linear siblings, that it’s now becoming rare to see an old-style three-terminal regulator. Modern designs have ...

Previously, I compared space-grade isolated DC-DCs and switching POLs, which resulted in lots of interesting discussion between us. With so much emphasis on cost, I was recently asked by a customer to ...

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 ...

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 ...

Nearly every new design tries to add functionality while using less power. Recent products from Infineon Technologies, National Semiconductor, Ricoh Europe BV, and Dialog Semiconductor all seek to ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

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 ...
