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 ...

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 ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently in practical circuits. A Joule Thief circuit is a small, energy-efficient ...

Is it possible to design an unconditionally stable linear voltage regulator? In fact, many believe that most regulator ICs are unconditionally stable. The answer is both simple and complex, if it is ...

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 ...

We return for a second wind and to the surface for air as we catch our breath in Part 4 by considering two categories of application circuits for the TL431. The loop gain is significantly reduced by ...
