We submerge somewhat deeper into analysis of the seemingly simple TL431 voltage reference with transconductance amplifier to find that some useful design parameters are missing from the manufacturer ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

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 ...

Download this article in PDF format. Analog semiconductor companies release buck-regulator chips so often you might think nothing of it. Yet there’s an enormous amount of work that goes into getting ...

Nerd Ralph loves cheap and dirty hacks, and for that we applaud him. His latest endeavor is a LiFePO4 battery charger that he made out of parts he had on hand for under $0.50 US. (Although we think he ...

National’s family of Simple Switcher step-down voltage regulators offers a wide input voltage range from 4.5V to 42V, which allows for wide-voltage transients from 12V and 24V input rails. Internal ...

Low dropout (LDO) regulators play a very important role in the power management of an integrated circuit. As a result, mindful designing and selection of LDO circuits become crucial. This article ...

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 ...

In this part, we go to greater depths to look at TL431 dynamics. Adjust your air regulator for the deeper dive. What is seen in the data sheet plots of gain and output resistance for some ...
