In this guide, we explain the Voltage Regulator Module (VRM) in simple terms for everyone to understand. For the optimal performance and longevity of electronics, it is important to maintain stable ...

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 ...

Voltage-regulator design for high output currents can be a critical and difficult task. Although voltage regulators with 1A maximum output current are simple to design, thanks to 78xx three-terminal ...

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 ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...

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 on, the fully powered switch-controlled fan ...
